KUBÁTOVÁ A., HUBKA V. (2021): Records of the rare and extremely osmophilic fungi Penicillium eremophilum and Xerochrysium dermatitidis on soy bars.   [food-borne fungi, food spoilage, Eurotiomycetes, Eurotiales, Aspergillaceae, xerophiles.]  Czech Mycology 73(2): 185-198   (published: 3rd November, 2021)
  abstract   The strongly osmophilic and slowly growing fungi Penicillium eremophilum and Xerochrysium dermatitidis were found on soy protein bars. These fungi are worldwide rarely recorded and have been recorded in the Czech Republic for the first time. Penicillium eremophilum is exceptional in the genus Penicillium by the production of 2-spored asci and by the absence of a conidial state. Xerochrysium dermatitidis is predominantly known from food, but some affinity to clinical material has also been recorded. The identification of the strains was confirmed by DNA sequencing. Their macroscopic and microscopic descriptions with photographs completed with known literature data are given.

NOVÁKOVÁ A., KUBÁTOVÁ A., SKLENÁŘ F., HUBKA V. (2018): Microscopic fungi on cadavers and skeletons from cave and mine environments   [European caves, abandoned mines, dead bodies, bones, mammals, frogs, spiders, isopods, micromycetes]  Czech Mycology 70(2): 101-121   (published: 19th August, 2018)
  abstract   During long-term studies of microscopic fungi in 80 European caves and mine environments many cadavers and skeletons of animals inhabiting these environments and various animal visitors were found, some of them with visible microfungal growth. Direct isolation, the dilution plate method and various types of isolation media were used. The resulting spectrum of isolated fungi is presented and compared with records about their previous isolation. Compared to former studies focused mainly on bat mycobiota, this paper contributes to a wider knowledge of fungal assemblages colonising various animal bodies in underground environments.The most interesting findings include ascocarps of Acaulium caviariforme found abundant on mammals cadavers, while Botryosporium longibrachiatum isolated from frogs, Chaetocladium jonesiae from bats and Penicillium vulpinum from spiders represent the first records of these species from cadavers or skeletons.

TALIGOOLA H.K., ISMAIL M.A., CHEBON S.K. (2011): Mycobiota and aflatoxins associated with imported rice grains stored in Uganda.   [rice grain, xerophilic fungi, nephrotoxigenic penicillia, Fusarium, aflatoxins]  Czech Mycology 63(1): 93-107   (published: 10th August, 2011)
  abstract   Milled rice grains imported into Uganda from Pakistan were investigated for natural contamination by fungi and aflatoxins. The direct plating method using five isolation media was used to enumerate and isolate the fungi during a 270-day storage period. Fungi were isolated and identified to species level and the percentage contamination levels were calculated. A total of 35 species belonging to 16 genera were recorded. The broadest species spectrum were found in the genera Aspergillus, Penicillium, Eurotium and Fusarium, which were represented by 11, 7, 4, and 3 species, respectively. Throughout the storage period, xerophilic fungi including Aspergillus candidus, Eurotium amstelodami and E. chevalieri were predominantly isolated. Species of the genus Penicillium (particularly P. pinophilum) and its teleomorph Talaromyces ranked second in predominance, while Aspergillus flavus, Fusarium spp. and other field fungi occurred only sporadically. Aflatoxins were recorded in rice samples during most storage periods with one sample recording 20–50 ppb. The moisture content increased in rice grains attaining values of over 14 % from the 180th day of storage onwards. A positive correlation was observed between moisture content and incidence of xerophiles, including A. candidus and E. amstelodami.

ŠIMONOVIČOVÁ A. (2001): Supplement to the Checklist of non-vascular and vascular plants of Slovakia. The species of microscopic fungi of the order Eurotiales.   [new records of microscopic fungi (Eurotiales), Checklist of non-vascular and vascular plants of Slovakia]  Czech Mycology 53(2): 173-188   (published: 20th February, 2002)
  abstract   Submited are 50 species of microscopic fungi of the order Eurotiales, which are not listed in the Checklist of non-vascular and vascular plants of Slovakia, part Fungi (Lizoň and Bacigálová 1998). The first group is presented by those microscopic fungi which were isolated only once so far. So we consider them to be scarce or rare. From among 30 species of microscopic fungi more than a halfbelongs to the genus Penicillium (16 species ) or genus Aspergillus (6 species ). The genera Eupenicillium, Eurotium and Paecilomyces have two new species, Emericella and Merimbla only one species. The second group is presented by more frequently isolated species of microscopic fungi. From among 20 species the genus Penicillium dominates with 8 species, followed by the genus Aspergillus with 4 species. Other genera(Byssochlamys, Dichotomomyces, Eupenicillium, Eurotium, Fennellia, Paecilomyces and Talarornyces) are presented with one or two species. From the total number of 50 species of microscopic fungi the prevailing part was isolated from different soils (73.3-75.0 %), from different food stuffs (3.3-30.0 %) and from other sources (23.3-45.0 %), including drinking water, dwellings and different materials in depositories and archives.

KRUPODOROVA T., BARSHTEYN V., KIZITSKA T., RATUSHNYAK V., BLUME Y. (2023): Antagonistic activity of selected macromycetes against two harmful micromycetes.   [ascomycetes, Aspergillus niger, basidiomycetes, dual-culture, Penicillium polonicum.]  Czech Mycology 75(1): 85-100   (published: 23rd June, 2023)
  abstract   Competition between 31 macromycete species and two harmful micromycetes Aspergillus niger and Penicillium polonicum was evaluated using dual-culture plate assay. All investigated fungi, except for Inonotus obliquus and Lepista luscina, possessed different levels of antagonistic activity against the tested micromycetes. Hypsizygus marmoreus and Lyophyllum shimeji were inactive against A. niger. Morchella esculenta and Oxyporus obducens were passive in the case of co-growth with P. polonicum. The study of fungal interactions showed variability in types of reactions and level of their visualisation. Co-cultivation of the studied species resulted in the following reactions: deadlock after mycelial contact and at a distance, partial or complete replacement after initial deadlock on contact. In general, the studied macromycetes showed moderate activity against the two micromycetes, as 11 species showed active and 7 species moderate antagonism. Results revealed higher antagonistic activity of macromycetes against P. polonicum than in A. niger co-cultures. Wood-decaying species Ganoderma lucidum and Trametes versicolor were the most active fungi against the two tested micromycetes with a maximal antagonism index. These findings provide valuable insights which can be further explored by means of in vivo assays to find a suitable agent for the biocontrol of diseases or spoilage caused by A. niger and P. polonicum.

GRISHKAN I., TEMINA M. (2023): Diversity of microfungal communities inside saxicolous lichens from Nahal Oren, Mount Carmel, Israel.   [endolichenic fungi, lichen thallus, melanised fungi, microclimatic contrast, rock surface.]  Czech Mycology 75(1): 15-34   (published: 28th March, 2023)   Electronic supplement
  abstract   In this study, we examined the endolichenic fungal communities of saxicolous lichens covering the rocks in the Nahal Oren valley, northern Israel. A total of 60 fungal species belonging to 35 genera were isolated from six lichen species collected in the summer and winter on the south-facing slope (SFS) and north-facing slope (NFS) of the valley. We verified that rocks serve as a possible source for the formation of endolichenic communities because communities colonising lichen thalli and the rock surface shared 39% of species and clustered together on the SFS. On the NFS, with a comparatively favourable microclimate, lichen thalli abundantly harboured typical soil fungi such as Clonostachys rosea and Fusarium spp. in winter and summer, respectively. At the same time, more severe environmental conditions on the SFS facilitated the prevalence of melanised fungi with thick-walled and multicellular spores irrespective of season. The lowest species richness and isolate densities of endolichenic communities were registered in the thalli of Collema cristatum. This decrease, especially expressed in the summer, was probably associated with the antifungal effect of substances produced by its cyanobiont, as well as with the heavy dehydration of thalli during the dry season.

AL-TOUBI A.S.S., AL-SADI A.M., AL-MAHMOOLI I.H., AL-HARRASI M.M.A., AL-SABAHI J.N., VELAZHAHAN R. (2022): Volatile organic compounds emitted by mycoparasitic fungi Hypomyces perniciosus and Cladobotryum mycophilum suppress the growth of Agaricus bisporus.   [antifungal, cobweb, ethanol, wet bubble, white button mushroom.]  Czech Mycology 74(2): 141-152   (published: 14th November, 2022)
  abstract   Hypomyces perniciosus and Cladobotryum mycophilum are mycoparasitic fungi infecting Agaricus bisporus and causing wet bubble and cobweb diseases, respectively. In this work, the role of volatile organic compounds (VOCs) emitted by these fungal mycoparasites in the suppression of A. bisporus was investigated. The VOCs of H. perniciosus and C. mycophilum effectively reduced the mycelial growth of A. bisporus by 60% and 73% after 5 days of incubation, respectively, compared to that of the control as assessed by the two-sealed-base-plates assay. Further, the VOCs of H. perniciosus and C. mycophilum were collected in a headspace solid-phase microextraction procedure, and their components analysed by means of gas chromatography-mass spectrometry. Ethanol was identified as the major volatile component in H. perniciosus and C. mycophilum. Ethanol vapour significantly retarded the growth of A. bisporus in an in vitro assay. The results of this study suggest that ethanol produced by H. perniciosus and C. mycophilum could be involved in the suppression of A. bisporus.

NOVOTNÝ D. (2022): Contribution to the endophytic mycobiota of aerial parts of oaks.   [endophytes, Czech Republic, Quercus robur, Quercus petraea, acorns, seeds, twigs.]  Czech Mycology 74(2): 111-121   (published: 1st July, 2022)
  abstract   The endophytic mycobiota inhabiting branches of Quercus petraea from two localities in the Křivoklát area, and branches, twigs and acorns of Quercus robur from one locality near the town of Semily were studied (all sites in the Czech Republic). Seventeen fungal taxa were isolated from branches of Q. petraea. Dominant fungi were found to be Colpoma quercinum and Phoma sp. as well as sterile dark mycelium and a black yeast-like fungus close to Sarcinomyces crustaceus. Eighteen fungal taxa were found in samples of aerial parts in Quercus robur. The most frequently isolated taxa were Pezicula cinnamomea, Colpoma quercinum, Alternaria alternata agg. and Acremonium sp.

SANTIAGO K.A.A., DELA CRUZ T.E.E., TING A.S.Y. (2021): Diversity and bioactivity of endolichenic fungi in Usnea lichens of the Philippines.   [antibacterial, anticandidal, antioxidant, lichen-associated, Sagada.]  Czech Mycology 73(1): 1-19   (published: 14th January, 2021)   Electronic supplement
  abstract   Endolichenic fungi (ELF; asymptomatic microorganisms living inside healthy lichen thalli) were isolated from three Usnea species, namely U. baileyi, U. bismolliuscula and U. pectinata, collected near the town of Sagada, Philippines. A total of 101 ELF were recovered representing 12 genera (classes Sordariomycetes and Eurotiomycetes), with the genera Nemania (50.5%, 51 isolates) and Xylaria (22.8%, 23 isolates) being the most abundant. Comparative analyses on the antimicrobial activities of lichens and ELF revealed that lichen crude extracts were effective against the Gram-positive bacterium Staphylococcus aureus and the yeast Candida albicans, while ELF crude extracts were effective against S. aureus, C. albicans and the Gram-negative bacterium Escherichia coli. The broad-spectrum nature of ELF has provided medicinal and industrial advantages over the slow-growing lichens as shown on their respective bioactivities. Extracts from ELF also had a higher total flavonoid content (TFC; 6.29–85.69 mg QE/g of extract) and stronger antioxidant activities (IC₅₀: 0.57–19.63 mg/ml) than lichen-derived extracts. Although only culturable ELF were identified, this study provides the first evaluation of the diversity and bioactivities of culturable ELF from fruticose lichens of the genus Usnea in the Philippines.

BHAVANA N.S., PRAKASH H.S., NALINI M.S. (2019): Antioxidative and L-asparaginase potentials of fungal endophytes from Rauvolfia densiflora (Apocynaceae), an ethnomedicinal species of Western Ghats.   [India, endophytic fungi, Penicillium chrysogenum, antioxidant, L-asparaginase, phenolic content.]  Czech Mycology 71(2): 187-203   (published: 19th December, 2019)
  abstract   This study focuses on the isolation and molecular characterisation of fungal endophytes from an ethnomedicinal plant, Rauvolfia densiflora (Apocynaceae), and an evaluation of antioxidative and L-asparaginase potentials. Fungal endophytes were isolated from leaf and stem parts of R. densiflora collected from the site of Talacauvery, Western Ghats, India. The highest colonisation frequency was found in leaves (95.5%), followed by stem parts (63.5%). A total of 19 fungal morphotypes belonging to 11 genera were identified by analysing the ITS sequences of the endophytes. The strains were screened for asparaginase production by qualitative plate assay and quantification by Nesslerisation. Maximum activity was recorded in the Penicillium chrysogenum culture (3.77 IU/ml). Submerged fermentation and ethyl acetate extraction were carried out to obtain secondary metabolites for the evaluation of total phenolic content (TPC) and antioxidative potentials. The TPC of fungal extracts ranged from 12.37 to 89.29 mg GAE/g dry extract and the IC value of scavenging activity from 26.64 to 547.23 μg/ml. The P. chrysogenum strain 50 (MH392736) was found to have the potentially highest total phenolic content and a high antioxidant capacity. This is the first report on the characterisation of fungal endophytes from R. densiflora and their antioxidative and L-asparaginase potentials.

NOVOTNÝ D., LUKÁŠ J., BROŽOVÁ J., RŮŽIČKOVÁ P. (2019): Comparison of the occurrence of fungi causing postharvest diseases of apples grown in organic and integrated production systems in orchards in the Czech Republic.   [Malus domestica, organic production, integrated production, Neofabraea, Penicillium.]  Czech Mycology 71(1): 99-121   (published: 28th June, 2019)
  abstract   During the years 2013–2015, the occurrence of fungi causing postharvest diseases of apples was evaluated in three apple orchards with integrated and organic production systems in the Czech Republic. The postharvest disease fungi were more frequently recorded in fruits from organically cultivated apple trees (average 29.97%) than those from integrated production (17.67%). This difference is statistically significant. Neofabraea, Penicillium, Alternaria and a sterile grey mycelium were the most frequently recorded taxa in apples grown in organic and integrated production systems. There were also significant differences in the frequency of occurrence of the most frequent fungal taxa between years. In 2013 and 2014, Neofabraea was the most frequently isolated genus in both cultivation systems, whereas in 2015, Penicillium was the most frequently recorded genus also in both cultivation systems, which was likely caused by the low precipitation in the 2015 growing season.

PARVEEN S., WANI A.H., BHAT M.Y., PALA S.A. (2018): Comparative study of the antimycotic activity of aqueous and ethanolic extracts of Berberis lyceum and Rumex obtusifolius against selected rot fungi.   [plant extracts, phytochemicals, antimycotic effectiveness, minimum inhibitory concentration, inhibition zone]  Czech Mycology 70(1): 47-56   (published: 16th March, 2018)
  abstract   Two medicinal plants, Berberis lyceum and Rumex obtusifolius, were screened for the presence of various phytochemicals and for their antifungal activity. The phytochemical tests carried out in the present study demonstrated the presence of phenols, alkaloids, tannins, flavonoids, quinones and terpenoids in the plant extracts. Therefore, ethanolic and aqueous extracts of these medicinal plants were evaluated for their antifungal activity against Penicillium chrysogenum, Aspergillus niger, Cladosporium herbarum and Trichothecium roseum, using the agar well diffusion method. All the plant extracts at different concentrations showed significant antifungal activity against the tested fungi. Of the two plant extracts, B. lyceum showed stronger antifungal activity than R. obtusifolius. Ethanolic extracts of both plants showed stronger mycelial growth inhibition than aqueous extracts. The ethanolic extracts of B. lyceum showed the strongest antifungal activity against Penicillium chrysogenum (inhibition zone diameter of 41 mm) followed by the ethanolic extracts of R. obtusifolius against P. chrysogenum (inhibition zone diameter 39 mm). Hence, it is concluded that these medicinal plants have a broad-spectrum antifungal activity and are a potential alternative to reduce various fungal pathogens.

MOUBASHER A.H., ABDEL-SATER M.A., SOLIMAN Z.S.M. (2018): Diversity of yeasts and filamentous fungi in mud from hypersaline and freshwater bodies in Egypt.   [fungal diversity, alkalinity, Wadi El-Natrun, lakes, Ibrahimia Canal, River Nile, molecular characterisation, ITS]  Czech Mycology 70(1): 1-32   (published: 26th January, 2018)
  abstract   The diversity of yeasts and filamentous fungi in muds from hypersaline alkaline lakes of Wadi ElNatrun and fresh water of the Nile River and Ibrahimia Canal was evaluated. The mean pH of saline water mud was 9.21, but fresh water mud registered 8.07. A total of 193 species (two varieties were distinguished in two of them) belonging to 67 genera were recovered from both muds investigated on DRBC (55 genera, 164 species), DG18 (36 genera, 117 species) and MY50G (23 genera, 76 species) media. From these, 17 species assigned to 12 genera were yeasts and 176 species and 2 varieties assigned to 55 genera were filamentous fungi. The highest numbers of fungal propagules were recovered on DRBC from freshwater mud, while the lowest on MY50G from saline water mud. Yeasts constituted a small proportion of all propagules from the two mud types on all three media, whereas filamentous fungi were the major component. However, freshwater mud samples yielded higher numbers of yeast genera and species using all three media. Candida was common in freshwater mud and rare in saline water mud, while Meyerozyma and Rhodotorula were infrequent in both muds. The remaining yeast species were recovered from freshwater mud only. Aspergillus (46 species) was the most common genus of filamentous fungi encountered in all samples, ranging in frequency from 39.82% to 96.62%; A. terreus, A. flavipes and A. niger dominated in both types of mud. Cladosporium (9 species), Fusarium (8 species), Penicillium (18 species) and Scopulariopsis (7 species) were encountered in both types of mud. Notably, 47 filamentous species were isolated only on the media with lower water activity (DG18, MY50G).

MARWA ABDEL-KAREEM M., ZOHRI A.A. (2017): Inhibition of three toxigenic fungal strains and their toxins production using selenium nanoparticles.   [Se-NPs, mycotoxigenic moulds, mycotoxins, aflatoxins, ochratoxin A, sterigmatocystin]  Czech Mycology 69(2): 193-204   (published: 24th November, 2017)
  abstract   Spoilage and poisoning of foods by microfungi are a major problem, especially in developing countries. While selenium nanoparticles (Se-NPs) have been used for a wide range of applications including antibacterial, antioxidant and anticancer applications, the effects of Se-NPs on fungal strains remain for the most part unknown to date. Our research is a pioneering attempt to evaluate the antifungal activity and antimycotoxin properties of Se-NPs (32 nm). Se-NPs at different concentrations were evaluated against the growth and mycotoxins production of three toxigenic fungal strains. The growth of Aspergillus parasiticus, A. ochraceus and A. nidulans was completely inhibited using 7000, 9000 and 3000 μg/ml of Se-NPs, respectively, while the complete inhibition in aflatoxins, ochratoxin A and sterigmatocystin production was reported by addition of 2000, 2000, and 800 μg/ml of Se-NPs, respectively. Results of this study show that Se-NPs were effective against the fungal strains tested and their toxin production. These results suggest that Se-NPs could be used as an effective microfungicide in agricultural and food safety applications against toxigenic microfungi.

  abstract   During an investigation into endophytic fungi associated with pomegranate in the South Khorasan Province of Iran, 2015–2016, five isolates were recovered with the morphological and molecular characteristics of Quambalaria cyanescens. The present study is the first fully documented report of Q. cyanescens from Iran, providing insight into its geographic distribution and host range. Our study is also the first report of occurrence of Q. cyanescens as an endophyte in a member of the Lythraceae family.

ABDEL-SATER M.A., MOUBASHER A.H., SOLIMAN Z.S.M. (2016): Diversity of filamentous and yeast fungi in soil of citrus and grapevine plantations in the Assiut region, Egypt.   [Mycobiota, biodiversity, phenotypic and biochemical characterisation, ITS sequence, Coniochaeta canina, Aspergillus stella-maris]  Czech Mycology 68(2): 183-214   (published: 20th December, 2016)
  abstract   An extensive survey of soil mycobiota on citrus and grapevine plantations in Sahel-Saleem City, Assiut Governorate, Egypt was carried out using the dilution-plate method and 2 isolation media at 25 °C. Sixty-four genera and 195 species of filamentous fungi and 10 genera and 13 species of yeasts were recovered. A higher diversity (number of genera and species) and gross total counts were recovered from citrus than from grapevine soil. The peak of filamentous fungi recovered from both soils was found to be in February. Aspergillus (45 species) was the most dominant genus; A. ochraceus predominated in citrus plantations, while A. niger and A. aculeatus in grapevine. The Penicillium count came second after Aspergillus in citrus (23 species) and after Aspergillus and Fusarium in grapevine (11 species).Penicillium citrinum, P. ochrochloron and P. olsonii were more common in citrus plantations, but they were replaced by P. oxalicum in grapevine soil. Fusarium (19 species) was represented in 88.9–100% of both soils on both media; F. solani predominated in both soils, while F. incarnatum came next in citrus, and F. babinda and F. oxysporum in grapevine. Humicola (3 species) with the dominant H. fuscoatra was recorded in 61.1–83.3% of soil of both plantations, while Talaromyces (with T. purpureogenus followed by T. pinophilus being the most common) was recorded in 83.3–100% on DRBC and 38.9–50% on DYM from the soil of plantations of both crops. Volutella (5 species) was common in citrus but missing from grapevine soil. The present study reveals that hyaline fungi predominated over dark-coloured ones. Yeasts comprised only minor proportions in both soils (maximum 0.5%). They showed their peak in the soil of citrus plantations in April and in grapevine in February. All species were recovered in one or two samples only. Diutina catenulata, Debaryomyces hansenii, Galactomyces (3 species), Hanseniaspora occidentalis, Kluyveromyces marxianus, Meyerozyma caribbica, and Schwanniomyces pseudopolymorphus were encountered in citrus only, while Cryptococcus laurentii, Pichia kudriavzevii, Meyerozyma guilliermondii and Rhodotorula sp. in grapevine only. Physiological and growth characteristics were obtained for most of the recovered yeasts.

PARVEEN S., WANI A.H., BHAT M.Y., KOKA J.A. (2016): Biological control of postharvest fungal rots of rosaceous fruits using microbial antagonists and plant extracts - a review.   [biological control, postharvest diseases, microbial pesticides, rosaceous fruits]  Czech Mycology 68(1): 41-66   (published: 1st February, 2016)
  abstract   This article aims to give a comprehensive review on the use of microbial antagonists (fungi and bacteria), botanicals and compost extracts as biocontrol agents against different pathogenic fungi causing postharvest fungal rots in rosaceous fruits which shows that they can play an important role in the biomanagement of fungi causing rot diseases. Plant extracts reported in the literature against pathogenic fungi indicate that they can act as a good biological resource for producing safe biofungicides. However most of the work has been done under experimental conditions rather than field conditions. There is still a need for research to develop suitable formulations of biofungicides from these microbial biocontrol agents and plant extracts. The review reveals that extensive ecological research is also required in order to achieve optimum utilisation of biological resources to manage various postharvest diseases of fruits.

(2015): Leaf surface and endophytic fungi associated with onion leaves and their antagonistic activity against Alternaria porri.   [phyllosphere, phylloplane, endophytes, purple blotch disease, antagonism]  Czech Mycology 67(1): 1-22   (published: 10th April, 2015)
  abstract   Sixty-eight fungal species belonging to 29 genera were isolated as leaf surface and endophytic fungi from healthy and purple blotch diseased onion leaves. The fungal populations associated with diseased onion leaves (1.360 × 103 CFU/g leaf in the phyllosphere, 2.614 CFU/leaf segment in the phylloplane and 1.324 CFU/leaf segment in the surface-sterilised diseased leaves) were higher than those in healthy samples (0.804 × 103 CFU in the phyllosphere, 1.184 CFU in the phylloplane, and 0.35 CFU as endophytes). Endophytic fungi of healthy leaves were represented by 12 genera and 15 species, while fungi of surface-sterilised diseased leaves included 17 species from 13 genera. The mycobiota associated with surface-sterilised diseased leaves were different from the endophytic fungi of healthy samples, whereas the disease may stimulate colonisation of opportunistic fungi causing secondary infections such as Botrytis cinerea, Penicillium aurantiogriseum, Alternaria alternata and Cladosporium spp. In contrast, healthy leaves were a source of antagonistic endophytic fungi such as Trichoderma harzianum and T. koningii. Testing the antagonistic effect of 91 fungal isolates against Alternaria porri showed that nine isolates of Trichoderma produced the highest suppressive potential (73.1%) depending on competition and mycoparasitism. Epicoccum nigrum and Penicillium oxalicum exhibited antibiosis against A. porri producing a 12 mm broad inhibition zone. In conclusion, the quantitative and qualitative compositions of fungi associated with onion leaves were distinctly influenced by A. porri infection. Mycobiota associated with asymptomatic onion leaves such as Epicoccum nigrum, Penicillium oxalicum and Trichoderma harzianum are a natural source of eco-friendly bioagents. They showed an effective antagonistic potential against A. porri, and may thus be applied as an alternative to fungicides.

ISMAIL M.A., ABDEL-HAFEZ S.I.I., HUSSEIN N.A., ABDEL-HAMEED N.A. (2013): Contribution to physiological and biochemical diagnostics of Fusarium taxa commonly isolated in Egypt.   [Fusarium, taxonomy, physiological features, acetylmethylcarbinol, diagnostic]  Czech Mycology 65(1): 133-150   (published: 10th June, 2013)
  abstract   Fusarium isolates belonging to 24 species and 8 sections were subjected to 11 growth, physiological and biochemical tests (166 isolates). All species were able to grow on 25% Glycerol nitrate agar (G25N), Mannitol medium, Czapek iprodione dichloran agar (CZID) and Dichloran chloramphenicol peptone agar (DCPA). Growth rate, colony colour and reverse on G25N and CZID were promising diagnostic criteria for separating species within sections. The growth rate and reverse on Mannitol agar was diagnostic not only for separation of F. oxysporum from F. solani, but also for separation of many other Fusarium species treated. The ability to grow on Tannin-sucrose agar could distinguish some species of sections Liseola and Sporotrichiella. Acid production on Creatine-sucrose agar distinguished some species of section Liseola and F. trichothecioides of section Discolor. Acetylmethylcarbinol production revealed for the first time that all isolates of F. subglutinans can produce this substance, while most remaining isolates lacked this ability. Tests for peroxidase, urease and pyrocatechol oxidase proved to be very useful. The phosphatase enzyme seems to be common in Fusarium species and therefore it is only diagnostic for F. camptoceras (negative results). Some physiological features could be used as criteria to distinguish some sections or species within the same section.

SAWMYA K., VASUDEVAN T.G., MURALI T.S. (2013): Fungal endophytes from two orchid species - pointer towards organ specificity.   [fungal endophytes, environment, orchids, Bulbophyllum neilgherrense, Pholidota pallida]  Czech Mycology 65(1): 89-101   (published: 10th June, 2013)
  abstract   Fungal endophytes may influence plant communities by altering the host’s fitness either positively or negatively. Little is known, however, about their host/organ specificity, life style and role in plantfungus symbiosis under varying environmental conditions. We compared the leaf and root endophyte assemblages of two orchids (Bulbophyllum neilgherrense and Pholidota pallida) from natural forests and greenhouse conditions. Xylariaceae species were consistently associated with leaf and root tissues, while Guignardia and Pestalotiopsis were found predominantly in the leaf tissues of both orchids. Correspondence analysis of the endophyte assemblages showed that the endophytes exhibited distinct organ but little host specificity. More endophytes were shared by the two different orchids growing in the same location when compared to endophyte assemblages of a single orchid from different locations. Considering the influence of endophytes in shaping the host’s community, diverse habitats must be screened vigorously to address questions regarding the role of endophytes in hostendophyte interactions.

HORTOVÁ B., NOVOTNÝ D. (2011): Endophytic fungi in branches of sour cherry trees: a preliminary study.   [Prunus cerasus, Czech Republic, mycobiota, endophytic fungi]  Czech Mycology 63(1): 77-82   (published: 10th August, 2011)
  abstract   Sour cherry trees (Prunus cerasus L.) harbour various fungal groups, including endophytes. Branches of two different cultivars of sour cherry trees (Újfehértoi Fürtös, Érdi Bötermö) were sampled in May and July 2010 at two study sites in the Czech Republic. Alternaria alternata and coelomycete sp. 1 were the dominant species in branches collected at one site. Aureobasidium pullulans was the most frequent fungal species in branches from the other site. Both species were dominant in May and July.

ABDULLAH S.K., MONFORT E., ASENSIO L., SALINAS J., LOPEZ LLORCA L.V., JANSSON H.B. (2010): Soil mycobiota of date palm plantations in Elche, SE Spain.   [soil saprotrophic fungi, phytopathogenic fungi, Phoenix dactylifera, isolation methods]  Czech Mycology 61(2): 149-162   (published: 10th August, 2010)
  abstract   The mycobiota of soil from date palm (Phoenix dactylifera) plantations in Elche, SE Spain was examined using 23 soil samples and five isolation methods. One hundred and nineteen species assigned to 67 genera were isolated. The most frequent species were in decreasing order: Aspergillus fumigatus, A. niger, Neosartorya spinosa, Thielaviopsis punctulata, Chaetomium bostrychodes, Gilmaniella macrospora, Aspergillus candidus, Fusarium oxysporum, Rhizopus microsporus, Sordaria fimicola, Aspergillus terreus, Chaetomium murorum, Fusarium solani, Mucor racemosus, Penicillium citrinum and Thielaviopsis paradoxa. The thermotolerant and thermophilic species of Malbranchea cinnamomea, Myriococcum thermophilum, Rhizomucor miehei, Scytalidium thermophilum, Talaromyces emersonii, Thermoascus aurantiacus and Thermomyces lanuginosus were detected in various frequencies of occurrence. Our findings are compared with those from a similar survey of soil from date palm plantations in Iraq. Our study indicates that there is no characteristic mycobiota for soil in date palm plantations except for the more frequent isolation of some species well known as pathogens on date palm.

RAVIKUMAR M., SRIDHAR K.R., SIVAKUMAR T., KARAMCHAND K.S., SIVAKUMAR N., VELLAIYAN R. (2009): Diversity of filamentous fungi on coastal woody debris after tsunami on the southeast coast of India.   [tsunami, Bay of Bengal, southeast coast of India, woody litter, fungal diversity]  Czech Mycology 61(1): 107-115   (published: 29th September, 2009)
  abstract   Five coastal locations on the southeast coast of India severely disturbed after the tsunami on December 26, 2004 were surveyed for the occurrence of filamentous fungi on woody debris by means of short-term (1 month) and long-term (12 months) damp incubation. Short-term incubation revealed 26 mitosporic fungi (8 genera) ranging from 14 to 17 taxa per location with a total frequency of occurrence between 0.4 and 5.6 %. Aspergillus taxa were dominant and six of them were common to all locations.Long-term incubation yielded 35 fungi (25 genera) (22 ascomycetes, 1 basidiomycete and 12 mitosporic fungi). The total fungal taxa per location ranged from 25 to 28 with a total frequency of occurrence of 0.8 to 46.8 %. Corollospora gracilis was the most dominant ascomycete (46.8 %), while Cirrenalia tropicalis and Dictyosporium pelagicum dominated among mitosporic fungi (18 %). The total frequency of occurrence of 11 ascomycetes and four mitosporic fungi was above 10 %. Twelve ascomycetes and two mitosporic fungi were common to all locations. The richness of fungi was higher after long-term than short-term incubation. The occurrence of 61 fungal taxa in this study suggests that the tsunami-dumped woody litter on the southeast coast of India might have at least partially originated from the ocean, thus representing a mosaic of fungi existing in seawater and sediments.

ISMAIL M.A., TALIGOOLA H.K., NAKAMYA R. (2008): Mycobiota associated with baby food products imported into Uganda with special reference to aflatoxigenic aspergilli and aflatoxins.   [mycobiota, aflatoxigenic aspergilli, aflatoxins, imported baby foods]  Czech Mycology 60(1): 75-89   (published: 4th July, 2008)
  abstract   Five baby food products imported into Uganda were collected from different shops and investigated for contamination by fungi and aflatoxins. Forty-two species belonging to 21 genera in addition to some unidentified fungi were recovered on dichloran rose bengal chloramphenicol agar. Cornflakes followed by Cerelac were the most heavily contaminated products while Heinz mixed cereal was the least. Cladosporium sphaerospermum, Fusarium tricinctum and Penicillium oxalicum were the most predominant fungi. On the other hand, using Aspergillus flavus/parasiticus agar, 34 % of the samples were positive for aflatoxigenic aspergilli. Aflatoxigenic aspergilli constituted 78.8 % of all aspergilli and 4.9 % of all contaminating fungi. Samples from all products were contaminated with aflatoxigenic aspergilli, but samples of Cerelac were the most, while those of Porridge oats were the least. Aflatoxin analysis of food samples revealed that 9 out of 13 analysed samples were contaminated with aflatoxins in the range of 1–10 ppb (6 samples) and 11–20 ppb (3 samples). Only samples of Cerelac were aflatoxin–free, although aflatoxigenic aspergilli were detected in some samples. It was noted that samples of Cerelac had the least moisture content compared to the other products. Contaminated foods constitute a health hazard to human consumption. These foods, especially those for babies, must therefore be examined at regular intervals in order to assess their hygienic quality.

OSTRÝ V., ŠKARKOVÁ J., PROCHÁZKOVÁ I., KUBÁTOVÁ A., MALÍŘ F., RUPRICH J. (2007): Mycobiota of Czech wine grapes and occurrence of ochratoxin A and Alternaria mycotoxins in fresh grape juice, must and wine.   [mycobiota, grapes, grape juice, wine, ochratoxin A, Alternaria mycotoxins, HPTLC]  Czech Mycology 59(2): 241-254   (published: 28th December, 2007)
  abstract   The aim of this study was to monitor the mycobiota of wine grapes, occurrence of ochratoxigenic microfungi in wine grapes and occurrence of ochratoxin A and Alternaria mycotoxins in fresh grape juice, must and wine from domestic crops in the year 2004. Thirteen samples of wine grapes (white /nine samples/ and red /four samples/) were collected during harvesting in the Znojmo wine region, SE Moravia. One sample of a wine grape variety was represented by three subsamples of wine grapes, which were sampled in left, middle and right part of the vineyard. Five wine grape berries per bunch were randomly selected, plated onto Dichloran Rose Bengal Chloramphenicol (DRBC) agar, and incubated for 5–7 days at 25 °C. Alternaria alternata, Cladosporium herbarum, C. cladosporioides, Penicillium expansum, P. aurantiogriseum, P. spinulosum and Rhizopus nigricans were isolated from the samples. Ochratoxigenic microfungi, e. g. Aspergillus carbonarius, and other species of section Nigri, A. ochraceus, Penicillium verrucosum and P. nordicum, were not found in the samples.The HPTLC method for quantification of ochratoxin A (OTA) and Alternaria mycotoxins (alternariol (AOH), alternariol monomethyl ether (AME), altenuene (ALT), and tenuazonic acid (TeA)) in fresh grape juice (13 samples), must (13 samples) and wine (13 samples) was used. The limit of quantification (LoQ) was 8 ng/l for OTA, 1.5 μg/l for AOH, 1.5 μg/l for AME, 1.5 μg/l for ALT and 7.5 μg/l for TeA.Occurrence of OTA and Alternaria mycotoxins in fresh grape juice, must and wine was not proved.

JANKOWIAK R., ROSSA R., MIŚTA K. (2007): Survey of fungal species vectored by Ips cembrae to European larch trees in Raciborskie forests (Poland).   [ophiostomatoid fungi, Ips cembrae, Larix decidua, fungi associated with bark beetles]  Czech Mycology 59(2): 227-239   (published: 28th December, 2007)
  abstract   The species composition of fungi associated with Ips cembrae was studied in the Raciborskie forests, Poland. The fungi were isolated from overwintered adults, larvae, new adults and from galleries at various stages of development. The results showed that there was a great diversity of fungi associated with this insect. We isolated 2877 cultures, including 61 species. The most important group of fungi were ophiostomatoid species. From these, Ceratocystis laricicola, Ophiostoma brunneo-ciliatum and Graphium laricis were commonly detected, whereas eight other species occurred less frequently or sporadically. Ophiostoma ips is documented here as a new associate of I. cembrae. Ceratocystis laricicola was shown to be the primary invader occurring most frequently at early stages of brood development, particularly in the sapwood. Ophiostoma brunneo-ciliatum and G. laricis were secondary invaders following C. laricicola. In the later stages of brood development other ophiostomatoid fungi appeared.

REMEŠOVÁ J., KOLAŘÍK M., PRÁŠIL K. (2007): Microfungi on the kernels of transgenic and non-transgenic maize damaged by the European corn borer.   [Bt-maize, microfungi, plant protection, European corn borer, Zea mays]  Czech Mycology 59(2): 205-213   (published: 28th December, 2007)
  abstract   From 2002–2004 isolations were carried out to determine the kinds and abundance of microfungi from non-transgenic maize kernels damaged by the European corn borer (ECB) and from transgenic Bt-maize (enriched with delta-endotoxin from the soil bacterium Bacillus thuringiensis). Bt-maize and non-transgenic maize (Zea mays) were grown at Praha-Ruzyně and Ivanovice na Hané, Czech Republic. Thirty-one taxa of filamentous microfungi were isolated, including eight zygomycetes and twenty-three ascomycetes (anamorphic stage). Presence of ECB, corn treatment, year, locality and isolation method significantly accounted for differences in fungus communities. Bt-maize was significantly different from the treatments with non-transgenic hybrids and was often associated with the potentially toxinogenic fungi Alternaria alternata and Epicoccum nigrum. Conversely, Bt-maize had lower incidences of Fusarium spp. and Acremonium strictum.

LYSKOVÁ P. (2007): Saprotrophic microscopic fungi and dermatophytes accompanying infections of the skin and nails of patients in the Moravian-Silesian Region (Czech Republic).   [saprotrophic microscopic fungi, dermatophytes, superficial mycose, Scopulariopsis brevicaulis]  Czech Mycology 59(1): 125-137   (published: 28th June, 2007)
  abstract   Over a 19-month period, the spectrum of saprotrophic microscopic fungi isolated from 245 patients in the Moravian-Silesian Region (Czech Republic) was analysed. Saprotrophic microscopic fungi were isolated from nails (90 %) and skin (10 %). None was isolated from hair. The material was the most frequently positive for the presence of Scopulariopsis brevicaulis (32.6 %) followed by Cladosporium sphaerospermum (5.3 %), Aspergillus versicolor (4.0 %), Geomyces pannorum (4.0 %) and others.Dermatophytes and saprotrophic microscopic fungi were both studied within one year and represented 1110 isolates. Dermatophytes were isolated in most of the cases and represented 943 isolations (85 %). The saprotrophic microscopic fungus Scopulariopsis brevicaulis is a known causative agent of onychomycosis. In the evaluation including dermatophytes it ended in the 3rd position with 5.2 % of isolations behind Trichophyton rubrum (80 %) and T. mentagrophytes (8 %).

Colloquium „Fungi as Model Organisms in Research and Biotechnology - III“ Olomouc, Czech Republic, 2 September 2005.  Czech Mycology 57(3-4): 307-323   (published: 10th February, 2006)
  abstract   The colloquium was a continuation of the previous scientific meetings that took place in Olomouc in 1999 and 2002 (Czech Mycology 52: 139-178, 2000 and 55: 103-149, 2003). It was organised by the Commission for Experimental Mycology of the Czechoslovak Microbiological Society and the Czech Scientific Society for Mycology together with the Institute of Biology, Faculty of Medicine of Palacký University, Olomouc. The aim of the colloquium was to provide a platform for a broad discussion on experimental mycology in all branches of basic and applied research. Besides two plenary lectures, 8 short communications and 8 posters were presented. In total 32 researchers from the Czech and Slovak Republics took part in the colloquium and discussed various topics important for the further development of experimental mycology. Abstracts of the contributions are given here.

HASHEM M. (2004): Biological control of two phytopathogenic fungal species isolated from the rhizoplane of soybean (Glycine max).   [biological control, soybean, Macrophominaphaseolina, Rhizoctonia solani]  Czech Mycology 56(3-4): 223-238   (published: 22nd December, 2004)
  abstract   Two hundred isolates representing 31 fungal species (20 genera) were recovered from soybean roots. Samples were collected from 12 localities at 3 different growth stages of the crop. The most dominant species were Aspergillus flavus, Fusarium oxysporum, Fusarium solani (Nectria haematococca), Macrophomina phaseolina and Rhizoctonia solani. Pathogenicity tests have proved the ability of Macrophomina phaseolina and Rhizoctonia solani to infect soybean roots and produce the symptoms of damping-off and root-rot diseases.The efficacy of three antagonists (Trichodermaharzianum, Epicoccum nigrum and Paecilomyceslilacinus) as well as two organic compounds (Strom and F-760) was evaluated as to their control of pathogenic fungi . Biocontrol fungi significantly suppressed Macrophominaphaseolina and Rhizoctonia solani in vitro and in vivo. Epicoccum nigrum and Paecilomyces lilacinus suppressed the growth of the pathogens by producing an inhibition zone while Trichoderma harzianum suppressed them by overgrowing. Strom and F-760 showed lower reduction effect of diseases in comparison with the antagonists.

FARGHALY R.M., GHERBAWY Y.A.M.H., YOSEF M.S. (2004): Contamination of meat stored in home refrigerators in Qena (Egypt).   [microscopic fungi, stored meat, refrigerators, Aspergillus, RAPD-PCR]  Czech Mycology 56(1-2): 53-62   (published: 12th August, 2004)
  abstract   Eighty samples were collected from different parts of home-refrigerators and meat stored herein, in the province of Qena, Egypt. Quantitative and qualitative estimations of moulds were carried out by conventional methods and the identified Aspergillus spp. were confirmed by the RAPD-PCR technique in the Institute of Applied Microbiology (IAM), University of Agricultural Sciences, Vienna, Austria. The obtained results revealed that the highest mould count was 3.9 X 104 CFU/cm2 in the chest of there frigerators, followed by 3.2 X 10^4, 2.6 X 10^3 and 2.5 X 10^3 CFU/cm2 in samples of air and freezer of refrigerators and stored meat, respectively. Elevenmould genera could beidentified, the most common of which were Aspergillus, Penicillium and Cladosporium. The counts and relative frequencies for these genera were 31 (25.4 %), 17 (13.9 %) and 16 (13.1 %), respectively. Five Aspergillus species were identified; mainly A. flavus 13 (42.0 %), A. niger 5 (16.1 %) and A. nidulans 5 (16.1 %). The isolated Aspergillus species were subjected to further identification by r and om amplified polymorphic DNA (RAPD) by using type strains from IAM. RAPD-analysis indicated that the Aspergillus strains isolated during this study were completely identical with the corresponding type strains from IAM. Public health hazard and significance of mould contamination in home-refrigerators, as well as hygienic measures and recommendations are fully discussed to prevent or minimise such contamination.

GIRIVASAN K.P., SURYANARAYANAN T.S. (2004): Intact leaves as substrate for fungi: distribution of endophytes and phylloplane fungi in rattan palms.   [phylloplane fungi, endophytes, Calamus, India]  Czech Mycology 56(1-2): 33-43   (published: 12th August, 2004)
  abstract   Leaves of twelve species of Calamus from southern India were screened simultaneously for the presence of phylloplane and endophytic fungi. Sampling of 2400 leaf segments yielded 824 endophyte isolates belonging to 34 species. Thirty species of phylloplane fungi were recorded. Several fungal species were found to be shared as endophytes by different hosts. However, the overlap between endophyte assemblage and phylloplane fungi of each host was low, suggesting that these two distinct groups of fungi occupy different niches, there by avoiding competition.

  abstract   The oak bark beetle (Scolytus intricatus, Scolytidae, Coleoptera) was studied during the years 1997-2003 with respect to the occurrence of microscopic fungi on the surface of its body. Samples were collected in eight localities in the Czech and Slovak Republics. The investigation was focused on all different stages of the beetle’s life cycle: eggs, larvae, adults be for e emergence, adults in generation and maturation feeding (nearly 600 samples), and also on galleries (400 samples). The most frequent fungi associated with S. intricatus were yeasts, Geosmithia spp. and Penicillium spp. Ophiostomatoid fungi were isolated, too. Great attention was paid to the occurrence of Geosmithia spp., which were so far recorded rarely. They were frequently found in all stages of the life cycle of Scolytus intricatus, except for males in maturation feeding. The ecology of Geosmithia spp. in feedings of phloem inhabiting insects is discussed for their negative cellulase production and the ecology of associated insect species. Trees infested with Scolytus intricatus represent a major and still little explored niche of Geosmithia spp.

  abstract   A survey on airborne thermophilous fungi at a farmhouse in Chennai, India was made using an Andersen 2-stage viable sampler for the period from January 1997 to December 1997 at fortnight intervals. A total of 582 colonies belonging to 17 species were recorded. The species Emericella nidulans was dominant with an average of 60.2 CFU/m³ of air followed by Aspergillus fumigatus and Thermomyces lanuginosus with 34.7 CFU/m³ of air and 32.2 CFU/m³ of air, respectively. The total respirable fraction recorded was 58.4 %.

MARIA G.L., SRIDHAR K.R. (2003): Endophytic fungal assemblage of two halophytes from west coast mangrove habitats, India.   [mangroves, halophytes, endophytes, fungi, India]  Czech Mycology 55(3-4): 241-251   (published: 22nd December, 2003)
  abstract   Twenty-five endophytic fungi comprising three ascomycetes, 20 mitosporic fungi and two sterile fungi were recovered from two halophytes (Acanthus ilicifolius and Acrostichum aureum) of a west coast mangrove habitat in India. Overall colonisation of tissue segments by endophytes ranged between 74.5 % (Acanthus ilicifolius) and 77.5 % (Acrostichum aureum). Analysis using the Jaccard’s similarity coefficient revealed 16-25 % similarity in endophyte assemblage among different tissues, and 24.5 % between the two hosts. Out of four tissues screened, species richness and diversity were high in stems of Acanthus ilicifolius and roots of Acrostichum aureum. The most dominant endophyte was Colletotrichum sp. in prop roots of Acanthus ilicifolius, and Yeast sp. 1 in rhizomes of Acrostichum aureum. Among the dominant endophytes (colonisation frequency >5 %), Acremonium and Yeast sp. 1 were common to both hosts. Acanthus ilicifolius showed dominance of a single species, (Colletotrichum sp.), while in Acrostichum aureum multiple species dominance was seen (Acremonium sp., Pénicillium sp. and Yeast sp. 1). Only one typical marine mitosporic fungus (Cumulospora marina) was recovered from the roots of Acanthus ilicifolius.

Colloquium "Fungi as Model Organisms in Research and Biotechnology - II", Olomouc, Czech Republic, September 5th–6th, 2002.  Czech Mycology 55(1-2): 103-149   (published: 23rd July, 2003)
  abstract   The colloquium was a continuation of a previous scientific meeting that took place in Olomouc in 1999 (Czech Mycology 52: 139-178, 2000). It was organised by the joint Commission for Experimental Mycology of the Czechoslovak Microbiological Society and the Czech Scientific Society for Mycology together with the Institute of Biology, Faculty of Medicine of Palacký University, Olomouc. The purpose of the colloquium was to provide a platform for a broad discussion on the use of fungi as model organisms in both basic and applied research. The programme of the colloquium was divided into four parts dealing with the following topics: biochemistry, biotechnology and genetics of fungi; phytopathogenic fungi; fungi pathogenic to humans and animals; and mycology of food and mycotoxins. Each topic was opened with a plenary lecture (30 min.), followed by short communications (10 min.) and accompanied by poster presentations. Besides five plenary lectures, 20 short communications and 24 posters were presented. In total 42 researchers took part in the colloquium and discussed various topics important for the further direction of experimental mycology. Abstracts of the contributions are given here.

NOVÁKOVÁ A., PIŽL V. (2003): Mycoflora in the intestine of Eisenia andrei (Oligochaeta, Lumbricidae) and in vermiculture substrates.   [cattle manure, saprotrophic and cellulolytic microfungi, earthworms]  Czech Mycology 55(1-2): 83-102   (published: 23rd July, 2003)
  abstract   Mycoflora of three commercial vermiculture systems based on cattle manure derived sub­ strates and Eisenia andrei earthworms was studied using several isolation methods. A total of 172 taxa of saprotrophic micromycetes were isolated (19 taxa of Zygomycetes, 9 taxa of Ascomycetes and 144 taxa of mitosporic fungi). Aspergillus fumigatus was the most frequent microfungal species in the intestine of Eisenia andrei. In vermicuture substrates, Aspergillus flavus and Aspergillus fumigatus were among species isolated very frequently by the soil dilution method, while Rhizopus stolonifer was estimated as frequent species using the soil washing isolation technique.

NOVOTNÝ D. (2003): A comparison of two methods for the study of microscopic fungi associated with oak roots.   [Quercus robur, oakdecline, Czech Republic, mycobiota, ophiostomatoid fungi]  Czech Mycology 55(1-2): 73-82   (published: 23rd July, 2003)
  abstract   Roots of four trees with symptoms of oak decline and roots of one healthy tree of Quercus robur were examined for the presence of fungi by using two methods (moist chambe rmethod and strong surface sterilisation method). Forty-five species were isolated in this project. Significant differences in composition of mycobiota based on the used method were detected. Fusarium solani, F. proliferatum, Sphaerostilbella aureonitens, Cylindrocarpon destructans, Pénicillium simplicissimum, P. purpurogenumvar. rubrisclerotium, Trichodermaviride, Ophiostomapiceae s.l. and Pénicillium glandicola were the most frequent fungi isolated by the moist chamber method. Cryptosporiopsis radicicola, dark sterile mycelium sp. 1, Cylindrocarpon destructans, ChaetomiuM globosum, Cylindrocarpon didymum, Pénicillium simplicissimum and Trichoderma koningii were dominant species observed by the method of strong surface sterilisation.

  abstract   The mycoflora of roots of three species of oak (Quercus robur, Q. petraea, Q. rubra) from two localities near Moravské Budějovice (southwest Moravia, Czech Republic) with and without tracheomycotic symptoms was studied. Fifty-seven species of fungi were identified from the samples. The most frequently isolated were Fusarium solani, Penicillium gl and icola, P. glabrum, P. simplicissimum and Acremonium curvulum. In the roots of trees with tracheomycotic symptoms two species of ophiostomatoid fungi were recorded. Abiotic condiontions (insufieciency of precipitation and higher average temperature) are considered to be primary reasons of oak decline.

(2001): The role of some saprophytic micromycetes and fungus Micromucor ramannianus var. ramannianus in forest soil.   [humic horizon, soil fungi, saprophytic micromycetes, Micromucorramannianusvar. ramannianus, biological soil functions, respiration, ammonification, nitrification]  Czech Mycology 53(2): 161-171   (published: 20th February, 2002)
  abstract   Different saprophytic micromycetes were isolated from the humic horizon (H-A 02) of different types of forest soils (barren l and of reforested waste dumps, cambisol of spruce, birch, European mountain ash, and blue spruce forests) in several areas (at Most in the Krušné hory (Ore Mts.), Jizerské hory (Izera Mts.)). Besides the spectrum of common species of soil micromycetes (Penicillium spp., Humicola spp., Trichoderma spp., Paecilomyces spp., Scopulariopsis spp., Aureobasidium spp., Mucor spp., Absidia spp.), the fungus Micromucor ramannianus (Möller) Arx var. ramannianus (Mortierella ramanniana (Möller) Linneman, Mucor ramannianus Möller) was regularly isolated from all types of soils, except barren soils of was te dumps. The biological quality of forest soils in connection with other biological characteristics was evaluated in relation to the presence and quantity of this fungus in forest soils. Basic biological processes (basal and potential respiration, ammonification, nitrification) show an increased intensity in forest soils in which the proportion of Micromucorramannianus v. ramannianus was not present in the soil of the worst biological quality (lower values of biological soil parameters), e.g. in of was te dumps. It is a topic for discussion whe the r this fungus can also be an indicator of environmental pollution.

  abstract   Mycelial dry weight, lipid and sterol contents of fungi tested varied with fungalgenus, species and even with isolate of one species. Their dry mass fluctuated between lll.6±l0.7-457.0±41.5 mg/50 ml medium. Lipids, sterols and ergosterol accumulated by the isolates tested ranged from 4.52±0.5-29.04±2.76%, 1.23±0.16-10.63±l.24% and 0.43±0.057-7.13±0.695% of their dry mass, respectively. Cochliobolus spicifer isolate No. 35 was the highest lipid-producer while Ulocladium atrum No. 90 proved to be superior in the production of sterols and ergosterol. TLC technique and chemical analysis of lipid classes produced by U. atrium No. 90 revealed that the lipid fractions are composed of free sterols, free fatty acids, sterol esters, glycolipids, phospholipids and squalene.

  abstract   Thirty-two species belonging to 19 genera of fungi were collected from 30 soil samples from the rhizosphere of pepper plants. The fungal colonies were characterised using classical morphological methods following identification keys. The most frequently isolated fungi were Chaetomiumglobosum, Fusarium oxysporum, Gliocladium roseum, Mucor racemosus, Myrothecium verrucaria, Penicillium aurantiogriseum, P. expansum and Trichoderma harzianum. The crude culture filtrate of Verticillium dahliae at 100% concentration caused sharp decrease in pepper seed germination. Chaetomium globosum, Gliocladium roseum, Myrothecium verrucaria, and Trichoderma harzianum produced a metabolite that retarded radial growth of Verticillium dahliae.

Colloquium "Fungi as Model Organisms in Research and Biotechnology", Olomouc, September 14th, 1999.  Czech Mycology 52(2): 139-178   (published: 20th April, 2000)
  abstract   The colloquium was organized by the joint Commission for Experimental Mycology of the Czechoslovak Microbiological Society and the Czech Scientific Society for Mycology. The purpose of the colloquium was to provide a platform for a broad discussion on the use of fungi as model organisms in both basic and applied research. The programme of the colloquium was divided into four parts dealing with the following topics: phytopathology, biotechnology and ecology, physiology and biochemistry, and medical mycology. Each topic was opened with a plenary lecture (30 min.), followed by short communications (10 min.) and accompanied by poster presentations. Besides four plenary lectures, 15 short communications and 21 posters were presented. In total 38 researchers took part in the colloquium, at who discussed various questions of importance for experimental mycology until late in the evening. Abstracts of the contributions are given here.

HASAN H.A.H. (2000): Fungal association and deterioration of Oil-type Safflower (Carthamus tinctorius L.) seed during storage.   [safflower, mycoflora, mycotoxin, oil, protein, sugars, enzymes, germination]  Czech Mycology 52(2): 125-137   (published: 20th April, 2000)
  abstract   Different fungal species viz. Aspergillus Jiavus, A. Jumigalus, A. niger, A. sydowii, Emericella nidulans, Mucorcircinelloides and Pénicillium chrysogenum were isolated from commercial safflower seeds. The total number of fungi increased with raising the moisture content of the seeds from 15 to 25 % and reached a maximum level after 3 months of storage. Aspergillus was the dominant genus at 25°C. However, Pénicillium was dominant at 10°C. Germination of seeds significantly decreased with increasing moisture content and length of storage. Where no germination in seed at 25 % moisture content was observed after 5 months of storage at v-â 25°C, there was a perceptible increase in freefatty acidscontent, especially at high moisture and temperatures. This increase in free fatty acids positively correlated with the infestation of seeds by P. chrysogenum at 10°C, and A. flavus and A. niger at 25°C. In artificially inoculated seeds (25 % moisture content) by A. Jiavus, aflatoxin production reached their maximum level after I month and then decreased. Seed deterioration was accompanied by a corresponding rise in free fatty acids, free amino acids and soluble protein. The high levels of autolytic enzymes (amylase, cellulase, lipase and protease) detected in seed fungi clearly indicate the important role of these enzymes in seed deterioration. Also, the carcurnin and turmerol oils of safflower promoted the growth and lipase activity of A. Jiavus. Thus, the oils encourage seed infestation and did not make the safflower safe from deterioration.

GHERBAWY Y.A.M.H., ABDELZAHER H.M.A. (1999): Isolation of fungi from tomato rhizosphere and evaluation of the effect of some fungicides and biological agents on the production of cellulase enzymes by Nectria haematococca and Pythium ultimum var. ultimum.   [Biologicalcontrol, root-rot, fungicides Nectria haematococca, Pythium ultimum var. ultimum]  Czech Mycology 51(2-3): 157-170   (published: 25th May, 1999)
  abstract   Forty-five species and two species varieties belonging to twenty-six genera of fungi were isolated from 30 soil samples from the rhizosphere of tomato plants. The fungi most frequently isolated were Aspergillus flavus, A.fumigatus, A. niger, A. terreus, Gibberella fujikuroi, Nectria haematococca and Rhizopus stolonifer. Ridomil and Vitavax-captan (10, 50 and 100ppm) had no significant effects on the activity of Cl and Cₓ enzymes of Nectria haematococca. Cₓ enzyme activity was slightly increased at 10 and 50ppm, but slightly decreased at 100ppm. Vitavax-captan (10, 50 and 100ppm) significantly decreased Cl enzyme activities of N. haematococca. Cₓ enzyme activity was slightly increased at 10 and 50ppm, but at 100 ppm it showed a slightly inhibitory effect. Ridomil caused a slight increase in the activity of Cₓ and Cl enzymes by Pythium ultimum var. ultimum at low and moderate doses but the highest dose of Ridomil caused a slight reduction. Vitavax-captan slightly increased the activity of Cₓ and Cl enzymes in P. ultimum var. ultimum. Normal and sterilised filtrates of Myrothecium verrucaria, Penicillium oxalicum and Trichoderma harzianum induced a small decrease in Cl enzyme activity of Nectria haematococca. The sterilised filtrates of the three fungi tested caused greater inhibition compared to the normal filtrate. The production of Cₓ enzyme was slightly increased with normal and sterilised filtrates of Penicillium oxalicum and Trichoderma harzianum, but was significantly increased by both types of filtrates of Myrothecium verrucaria. The two types of filtrate of all fungi tested did not significantly affect the activity of Cl and Cₓ enzymes by lithium ultimum var. ultimum. Production of extracellular protein by Nectria haematococca was not significantly affected by any dose of the tested fungi cides. It was slightly increased by the two types of filtrate of the three tested fungi but significantly increased by the normal filtrate of Myrothecium verrucaria. The normal filtrate of all the fungi tested enhanced extracellular protein production to a greater extent than the sterilised filtrate. Extracellular proteins of Pythium ultimum var. ultimum were slightly increased by all doses of Vitavax-captan and low doses only of Ridomil, also two types of filtrate of all tested fungi caused a slightly increasing effect.

  abstract   Data on the occurrence and inducibility of extracellular β-N-acetylhexosaminidase, α-galactosidase, α- and β-mannosidase and α-L-fucosidase, including inductors, are given for selected Aspergillus, Penicillium and Fusarium strains. These data represent additional information on the strains in the Culture Collection of Fungi, Department of Botany, Charles University, Prague, and in the Culture Collection of the Institute of Microbiology, Prague, Czech Republic, thus extending their usability in biochemistry and biotechnology. With respect to these biochemical data a taxonomic evaluation of the examined strains is presented. Several strains were re­ identified after biochemical and morphological comparisons with the type strains. The strains of A. niveus CCF 544, A. terreus CCF 76, CCF 869, and CCIM USA were re-identified as A. flavipes, the strain A. oryzae CCF 1301 as A. wentii.

  abstract   The activity of 2-thiocyanomethylthiobenzothiazole (TCMTB) and selected organotin com­ pounds (OTC = TBTO, TBTS, TBTCA and TBT-DEDTK) against moulds was evaluated by means of mycologicaltestsin which treated and subsequently naturally aged beechwood samples were exposed to the effect of a mixture of six moulds under laboratory conditions. Natural ageing of the treated samples took place under an angle of 45’, and during periods of 0, 2 or 4 months. TCMTB was characterized as the relatively most stable fungicide with antimould activity.

  abstract   The frequency of occurrence of fungi in 25 hair samples of nine kinds of sheep, collected from different localities in Saudi Arabia, was estimated using three isolation methods at 28°C. Fortyfive species and one variety representing 23 genera were isolated and the most common genera were Chrysosporium, Alternaria, Aspergillus and Penicillium. The most prevalent species of the above genera were C. indicum, C. tropicum, Alternaria alternata, Aspergillus flavus, A. fumigatus, Penicillium chrysogenum and P. oxalicum. Other fungi were also isolated with variable frequencies.

  abstract   The ciliostatic effect of metabolites from mycelia and spore biomass of 185 micromycete strains extractable with chlor of orm on tracheal epi the l cilia was investigated in 1-d old chickens in vitro. The strains were isolated from cotton or flax. Extracts of 54 strains (29 %) displayed ciliostatic activity: 16 (9 %), 6 (3 %), and 32 (17 %) strains stopped the movement of cilia after 24, 48, and 72 hours, respectively. There may be relationships between these results and respiratory tract illnesses in people living in mouldy dwellings, working with mouldy materials, or with sick building syndrome.

  abstract   Laboratory experiments were carried out to examine the effect of four fungicides on spore germinating potentialities, radial growth and survival of viable propagules in soil of five phytopathogenic fungal species. The test organisms were achieved from infected roots of wheat plants cultivated in the Assiut area, Egypt. These were: Altemaria alternata, Cochliobolus sativus, Drechslera halodes, Fusarium moniliforme and F. oxysporum. The fungicides reduced germ tube production and radial growth of all fungi, and the reduction increased with increase in concentration. The maximal reduction was recorded at 50 μg/ml. At this concentration, Homai prevented spore germination of all test species. Neither F. moniliforme nor F. oxysporum can grow on agar medium supplemented with 50 μg/ml of either Benlate or Homai. The suppressive effect of fungicides on spore survival in soil cultures was also noticed but seemed to be lower than in agar application. In certain treatments, the numbers of viable propagules of tested fungi were not significantly affected in autoclaved nor non-autoclaved soil.

  abstract   Species representation of micromycetes and their frequency were studied in the period 1981-1988 in four archives in Prague and near Prague and in one depository in West Bohemia. Representants of genera Penicillium, Cladosporium, Alternaria, Aspergillus, Mucor and Rhizopus isolated by sediment plate method and from the surfaces of the archive depots were the most frequent in all observed spaces. The higher number of the most frequent species was always found in older and for the archive purposes less convenient buildings, while inside the new building the number of the most frequent species was very low. In suitable conditions only a limited number of species for which the given specific conditions are convenient, act as destructive. They are mostly Penicillium which form coherent growing covers on the backs of the books and cartons. Spores of these fungi released by their growth contaminate the atmosphere of these spaces and can cause allergies in sensitive persons.

  abstract   The survival of fungi from soil samples has been investigated after temperature of 60, 70, 80 and 90"C in Sabouraud agar. The number of isolated propagules and species had significantly different quantities. The heat-resistant fungi are an economically and scientifically important group of fungi and represent a matter for further investigation.

  abstract   From multiple uses of fungi in early historic times, “early biotechnological processes” developed. Fungi were used here already e.g. for production of cheese, bread, wine, beer and other foodstuff. Based on these processes, fungi today have become one of the most important group of organisms in modern technology, where food, fodder and various metabolites such as antibiotics, enzymes, steroids etc. are produced on an industrial scale. An equally important role of fungi in biotechnology is also to be expected for the future where - in addition to existing uses - fungi will be increasingly used employing modern methods such as genetic engineering and will also new applications as in pollution control, biological control of pests, microbial leaching and even biotechnology.

  abstract   The nomenclature of fungi is controlled by the InternationalCode of Botanical Nomenclature, revised at intervals of six years. The latest revision by the XV International Botanical Congress in Tokyo in 1993 signalled a major shift in botanical nomenclature towards increased pragmatism. The “top-ten” changes relevant to mycologists are summarized, and attention is drawn to a resolution of the Congress urging taxonomists to refrain from name changes for non-scientific reasons. Discussions have also been taking place between representatives of the Codes or Rules regulating the names of other organisms with a view to increasing harmonization between their practices and the eventual production of a single Code. Significant common ground has been established and the formation of an International Commission on Bionomenclature has been proposed. The pressure for change comes from both the generators and the users of names, and has targets which if realized will be of benefit to both groups.

  abstract   The ciliostatic activity of the heat-stable (100°C/10 min.) and chloroform-extractable metabolites of 63 strains of filamentous fungi - growing on the liquid medium - on tracheal cilia of one-day-old chickens in vitro was evaluated. Twenty two (34.9%) from the investigated strains produced ciliostatic metabolites, 4.7%, 7.9%, 3.1%, resp. 19.0% of the strains stopped the movement of cilia after 24, 48, 72, resp. 144 hours. The results are discussed in connection with chronic bronchitis of people working with moulded materials or living in moulded dwellings.

  abstract   Numbers of colonies of micromycetes, which had been isolated from three soil samples, exposed to 80 'C heat for 60 minutes in Sabouraud agar, were counted. The pH of the agar varied (from 4 to 8), and sucrose (10-50 %), or natrium chloride (2-8 %) were incorporated in the agar. The most resistant germs in the experiment seemed to be the ones of Talaromyces avellaneus (Thom & Turesson) C. R. Benjamin which were present in the soil. The germs of Eupenlcillium baamense (van Beyma) Stolk & Scott were relatively equally sensitive to the experimental conditions as the germs of the Neosartorya físcheri (Wehmer) Malloch & Cain.

  abstract   Microscopic fungi were isolated from the enchytraeid Fridericia galba (Hoffmeister, 1843), and from surrounding soil. Isolation was done from aseptically squashed enchytraeid bodies and from enchytraeid excrements prepared by defaecation into sterile conditions. The cultivation media were soil extract agar, cherry decoction agar and beer wort agar. A total of 39 fungal species was found, 29 in the excrements and 19 in the soil. In most cases, fungi isolated from the soil differed from those isolated from the excrements. Feeding preference and seasonal variation were not demonstrated. Spores of fungi were viable after passage through the enchytraeid gut. The biochemical activity of the isolated fungi indicates preferential feeding on plant remains where the degradation of cellulose, pectin and xylose predominates.

  abstract   The aragonite coating in some pans of the caves in Zbrašov (northern Moravia, ČSFR) is strewn with fragments of textile fibres, originating probably from the clothes of cave visitors. These filaments as well as the aragonite in their close vicinity are colonised by microscopic fungi. About fifty taxa have been identified. Spores of fungi in the aeroplankton in the caves mostly belong to other species than do occur on the aragonite. The species composition of the fungal community on aragonite is probably influenced by the temperature inside the caves.

  abstract   On five localities in vallies Krížna, Koprová and Furkotská (High Tatra Mts.) we investigated the species structure of soil microscopic fungi and the similarity of mycocenosis. The arenic podzol and podzolic ranker soils were studied. The soils had low to very low acid reaction and very low content of organic matter. In the global number of isolated soil microscopic fungi species (48), the cosmopolitan genus Penicillium of the family Moniliaceae was dominantly represented. The species of the family Mucoraceae were suppressed as the result of the soil quality decreasing, which reflects the degradation of the quality of the whole environment in High Tatra Mts. The highest index of similarity – S = 0.6 – was proved between the localities in the neighboring vallies.

  abstract   Microfungal community structure in four forest localities in the Valley Tichá in the High Tatra Mountains was studied. Podzolic and ranker soils are poor in organic matter, physically and chemically unfavourable. The pH values are lower – by 1.0 to 1.5 – than values in 1962, which means that the quality of the soils has degraded. These differences correspond with the quality of mycocenosis, which has also worsened. 41 species of soil micromycetes were isolated. The occurrence of the representatives of the genus Penicillium (fam. Moniliaceae) was the highest. The occurrence of the representatives of the family Mucoraceae was suppressed. The similarity of the neighbouring mycocenoses was higher than that of those more distant from each other.

  abstract   The changes of fungal growth in laboratory experiments (estimation of mycelial biomass and colony diameter) were studied by cultivation of 10 species of soil fungi on media with different concentrations of the herbicides Basagran, Labuctril 25 and Oxytril CM. The subject fungi responded to increased concentrations of herbicide in different ways. Cladosporium herbarum (colony diameter) and Penicillium janthinellum (mycelial biomass) were the only investigations to show a similar response to all the herbicides. Penicillium janthinellum (mycelial biomass) was the only example of a significant stimulation of fungal growth. Changes in colony pigmentation and sporulation were also recorded.

  abstract   Microscopically (KOH with Parker ink) and semiquantitatively culturally ("ZOT" medium), 750 samples of skin scales from different areas of the body surface of 665 subjects (with or without dermatoses) were investigated for Malassezia furfur. This lipophilic yeast was isolated mostly from the capillitium, face and trunk (72–90% of samples). A total of 81.4% of samples were positive for M. furfur (65.6% microscopically and 73.5% culturally). In 57.7% of cases the yeast was observed by both methods. The average cultural detection was higher in samples with more microscopically visible blastoconidia. The results of M. furfur cultivation were influenced by several factors (e.g., subject preparation, timing of sample inoculation, cultivation conditions).

  abstract   Zygosporium mycophilum (Vuill.) Sacc. is described and illustrated from a decayed apple, rotten by Botrytis cinerea and various species of Penicillium, in Czechoslovakia. It seems that the species is not an obligate mycoparasite, but is obviously mycophilous, growing always among other microscopic fungi. Conidia were oval to ellipsoidal, hyaline, 5–8.5 × 4–6 µm, minutely verruculose. This collection is a first record from Czechoslovakia.

  abstract   Two strains of the rather rare micromycete Eladia saccula (Dale) G. Smith were isolated from forest soil in Czechoslovakia and Poland. They are maintained in the Culture Collection of Fungi, Department of Botany, Charles University, Prague (CCF 1978 and CCF 2391). Eladia saccula is reported from Czechoslovakia for the first time. A description is provided on several nutrient media (CZ, CYA, MEA, G25N, and beer wort agar) at 25 °C, 5 °C and 37 °C. The ability to grow at 37 °C is remarkable. Growth is reduced on medium with limited water availability (G25N). Based on typical conidiophore and phialide structures, placement in the genus Eladia is supported over Penicillium.

  abstract   In three archives in Prague and in Klatovy micromycetes from the atmosphere, archive documents, walls and shelves were studied. Altogether 88 species, mostly representatives of the Moniliales as well as Mucorales orders, Penicillium and Aspergillus species prevailed. The following species were among the most frequently isolated: Penicillium cyclopium, Cladosporium herbarum, C. cladosporioides, Alternaria alternata, Aspergillus niger, Penicillium chrysogenum, Rhizopus arrhizus and Aspergillus versicolor. The number of species rose with increasing relative humidity and deteriorated hygienic conditions in the storage areas. Fungi with weaker cellulolytic activity, utilizing bookbinding glues, were also verified to contribute to the destruction of archival documents. From a hygienic perspective, the presence of pathogenic species Aspergillus fumigatus and Rhizomucor pusillus is significant for archive staff.

BETINA V. (1986): Fungi in biotechnology-history, present times, perspectives.  Česká Mykologie 40(2): 65-73   (published: 10th May, 1986)
  abstract   A review of applications of fungi in biotechnology from the old ages to the present times is presented. Origins of vine and beer fermentation as well as leavened bread making are lost in the mist of antiquity and records of the production of Roquefort cheese go back about a thousand years. On the other hand, commercial production of yeast began in the last century and the production of single-cell proteins (SCP) was born in our century. Nowadays, fungi are further used in commercial production of enzymes, organic acids, vitamins, antibiotics and plant growth regulators, in biotransformations of steroids and antibiotics, in the ephedrin synthesis and in preparation of other pharmacologically useful substances. Great achievements were obtained by applying classical genetic methods. Possibilities of the use of protoplast fusion and recombination, gene amplification or recombinant DNA technology using restriction enzymes are discussed.

  abstract   In the present paper we summarize the results of electron microscope investigation of the hyphae of three singlespore isolates of Cercospora beticola and a sterile mutant. In ultrathin sections of hyphal cells we have found two types of viruslike particles of spherical shape, 30—35 and 50—55 nm in diameter. They were dispersed in the cytoplasm and occasionally in the vacuoles as well. Viruslike particles of both types occurred together in the hyphal cells of the strain Mss2, whereas the hyphal cells of strain PR13 contained viruslike particles only one dimension, i.e. there were cells containing 30—35 nm and others 50—55 nm viruslike particles. In the infected cells we observed changes of mitochondria, the occurrence of lamellar structures, changes of cell walls leading to the disruption and liberation of viruslike particles from the cells. The sporulation of infected strains was considerably lower than in healthy one.

  abstract   In three forest sites of the Nature reserve “Voděradské bučiny” soil microfungi were studied in the period from September 1978 to July 1979. A total of 66 species was identified, 9 of which belonged to Mucoraceae and 57 to Moniliales. The most common species were Penicillium albidum Sopp emend. Fass. (all sites) and Trichoderma viride Pers. ex S. F. Gray (beech forest, beech forest with Dicranum), Absidia cylindrospora Hagem (beech forest), P. spinulosum Thom (beech forest with Dicranum, spruce forest), P. chrysogenum Samson, Hadlok et Stolk (beech forest, spruce forest). The greatest number of species was found in the spruce forest. The highest biomass values of mycelium and of spores were ascertained in stony soil of the beech forest with Dicranum scoparium.

SEMERDŽIEVA M., WOLF A. (1982): Kernverhältnisse terminaler Zellen von Agrocybe aegerita.  Česká Mykologie 36(3): 160-165   (published: 1982)
  abstract   Yeasts were found in the mouths of 81.4% of persons with removable dentures; Candida albicans (alone or in combination with other yeasts) in 62.9%. Yeast incidence varied from 66% (31–40 years) to 95% (71–80 years). Findings are listed for tongue, teeth, and dentures. In dentures younger than one year, 49% were yeast-negative, while 21% showed massive/abundant yeast presence. In older than 4 years, 25% were negative and 55% positive. Clinical thrush was observed in 1.4%. The study also considered pathological changes under dentures, tongue and tonsil appearance, frequency of denture use, and use of antibiotics, corticoids, and cytostatics.

ČAČA Z. (1982): Present trends in the world phytopathological research.  Česká Mykologie 36(2): 65-71   (published: 15th May, 1982)
  abstract   Vararia granulosa (Fr.) Laurila is a name which cannot be applied to the fungus for which it is now commonly used. Fries (1838, 1874) considered the element representing our Vararia only a marginal part of his broad concept of Grandinia granulosa (Pers. ex Fr.) Fr. As there is no legitimate name for the fungus in question, Vararia borealis Pouz. spec. nov. is proposed for it here.

HUBÁLEK Z. (1981): A systematic survey of dimorphic and polymorphic fungi.  Česká Mykologie 35(4): 209-226   (published: 1981)
  abstract   Various definitions of the term dimorphism in fungi are briefly discussed and a general concept is given with a suggested morphological classification of the dimorphism. Dimorphism (and polymorphism) is delimited as an environmentally controlled reversible phenotypic duality (or plurality in the case of polymorphism) in the morphogenesis of the vegetative fungal cells, which is not restricted to pathogenic species and to the mycelial-yeast transitions only. A systematic list and an alphabetical index of the fungi exhibiting the phenomena of cellular dimorphism or polymorphism are presented.

ZAJÍCOVÁ S., JABLONSKÝ I., JAŠA B. (1981): The influence of substratum composition and cultivating method on fruit-body yield in Flammulina velutipes (Curt. Ex Fr.) Sing.  Česká Mykologie 35(3): 152-160   (published: 1981)
  abstract   In studies of the influence of optimal substratum composition on mycelia growth and fruit-body formation in Flammulina velutipes it was found out: the highest lineal daily mycelia growth rate was achieved on cultivating media from wheat straw (0.51 mm) and shredded corn cobs (0.50 mm). Cultivated on unsupplemented media the best yields were achieved on corn cobs (20.97%) and wheat straw (19.13%). The best yields were obtained from F. velutipes cultivated on corn cobs supplemented by a mixture of 10% bone meal and 12% wheat corn meal (28.4%). Evaluating the influence of different methods of cultivation on yield the following was found out: the optimal duration of media incubation by mycelia in supplemented corn cobs was 21 days, whereas in unsupplemented mixture sawdust:straw:corn cobs (ratio 1:1:1) the best yield was achieved after 35 days of incubation. By the reduction of the yielding surface by 2/3 a substantial increase in the average weight of fruit-bodies was obtained with a slight drop of yield as compared with plots with unlimited yielding surface. Sterilized media gave a yield which was higher by 1% than pasteurized ones.

BANDRE T.R., DAGINAWALA H.F. (1981): Mycoflora associated with various food commodities.  Česká Mykologie 35(1): 47-49   (published: 1981)
  abstract   Various fungal species were isolated and identified from 11 specimens of food commodities. Since many of the species belong among the potentially toxinogenic ones, the isolates will serve as the source material for the estimation of the real toxinogenity. These estimations are important in the field of hygienic toxicology of foods.

  abstract   With one third of the patients suffering from otitis there occur microscopic fungi in the ear swabs, but they can be considered agents of the disease in approximately one half of the positive findings only. During the last 15 years, fungi were cultivated from the ear swabs of 472 patients with various ear diseases, mostly otitis externa. The most frequent yeasts in otomycoses were Candida parapsilosis and C. albicans, while the most frequent Aspergillus species were A. fumigatus, A. flavus, and A. niger. Clinical pictures and treatment of some external otitides are briefly mentioned.

  abstract   Spores of the Aspergillus niger mutant MBU 90, producing high quantities of citric acid under submerged conditions, will keep their viability during a period of 4 years when stored in talc or in lyophilized form (using inactive horse serum or dried milk). When spores are stored in active coal a decrease in spore viability was noted after 3–4 years of storage. Moreover, an increase in the frequency of different morphological modifications was observed.

JANEČKOVÁ V., FASSATIOVÁ O., DANIEL M., KŘIVANEC K. (1977): Findings of soil microscopic fungi in the Himalaya Mountains (Nepal).  Česká Mykologie 31(4): 206-213   (published: 1977)
  abstract   Within the framework of the 1973 Czechoslovak expedition in the Makalu Mountain region in the Himalayas (East Nepal) a total of 43 soil samples were collected for mycologic examination. Fourteen genera with 37 species of soil fungi were isolated from the samples. Though the spectrum of the isolated microscopic fungi was not wide, it contained 2 genera (Acremonium and Tolypocladium) and 15 species described for the first time amongst the Himalayan mycoflora. Some of the species were collected in the area for the second time. Among the keratinophilic microscopic fungi, Chrysosporium lucknowense was isolated. The investigation and the collection of soil samples took place at the altitudes of 1000–4900 m in the sites where the presence of terrestrial mammals was established, or direct from lair openings. The aim was to detect potentially pathogenic or keratinophilic microscopic fungi. Various species of microscopic fungi were isolated for the first time from the extreme climatic conditions of the high mountains characterized by an increased occurrence of UV radiation, great temperature fluctuations, strong air flow, a decrease in the air pressure and oxygen content and extreme abiotic and biotic factors influencing the specific existence of the organisms.

  abstract   Contamination in 24 algal cultures from the collection of the Department of Botany, Charles University of Prague, was determined. All cultures were contaminated. They contained fungi, bacteria, actinomycetes, in some cases fungi along with bacteria. There were isolated 10 species of fungi: Verticillium lecanii (Zimm.) Viégas, Acremonium kiliense Grütz, Penicillium notatum Westl., Penicillium sp., Aspergillus nidulans (Eidam) Wint., Aspergillus versicolor (Vuill.) Tiraboschi, Tritirachium album Limber, Cladosporium sp., Paecilomyces sp., Acremonium sp. Contaminants were able to grow even in algal cultures cultivated on mineral media. Analysis of contamination indicated that some contaminants were brought into cultures from the original environment of algae, some of them by following manipulation with cultures.

HEJTMÁNEK M., HEJTMÁNKOVÁ N. (1976): Fluorescence microscopy of hyphal nuclei.  Česká Mykologie 30(1): 20-23   (published: 1976)
  abstract   A method of fluorescence staining of hyphal nuclei in 32 species of fungi is described. It also permits observation of nuclei in conidia and septa. The latter can be safely distinguished by combining fluorescence under incident UV light with phase contrast under penetrating light. This method is applicable to quantitative evaluation of nuclear ratios in mycelium of Phycomycetes, Ascomycetes, Basidiomycetes, and Deuteromycetes.

  abstract   Experimental infections were conducted in the Kladno coal mines using several strains of Trichoderma viride to control wood-decay fungi. Only one strain, isolated from a poplar branch parasitizing Chondroplea populea and Cytospora chrysosperma, was effective against Serpula lacrymans, Heterobasidion annosus, and Fomitopsis pinicola. This early biological wood protection attempt, though discontinued, offers potential for renewed research.
