HÝSEK J., BROŽOVÁ J. (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   In the study the following nomenclatural problems were solved: Mucor cylindrosporus Ling-Young, M. dimorphosporus Lendn., M. oudemansii Váňová, nomen novum, M. sciurinus Naumov and M. wosnessenskii Schostak. The following new combinations were realized: Mucor dimorphosporus Lendn. f. sphaerosporus (Hagem) Váňová, Mycocladus blakesleeanus (Lendn.) Váňová, Mycocladus corymbijer (Cohn in Lichth.) Váňová and Mycocladus ramosus (Zopf in Schenk) Váňová. Finally, the Latin diagnosis of the taxon Micromucor ramannianus (Moeller) v. Arx var. angulisporus Naumov ex Váňová was completed.

  abstract   In a woman with idiopathic atrophy of bone marrow, mucormycosis developed after treatment of dental pulpitis and periodontitis. The infection spread to the paranasal sinuses, orbit, and brain. Typical filaments of zygomycetes were found in histological sections, and Mucor pusillus Lindt was identified in cultures. This is the first human systemic mycosis in Czechoslovakia with cultivated Mucor pusillus.

  abstract   A case of nodose mucormycosis caused by Mucor pusillus was diagnosed in a six-month-old bull slaughtered due to chronic health issues. The mediastinal lymph nodes showed extensive caseous necroses. Histopathology confirmed the infection, and cultures yielded the causative agent. This represents the first reported case of its kind in Czechoslovakia.

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.

DEEPTHI A.S., RAY J.G. (2021): Ecological relevance of the endophytic fungal diversity in velamen roots of tropical epiphytic orchids.   [epiphytes, Orchidaceae, root-associated endophytes, Trichoderma, Endomelanconiopsis, Lasiodiplodia.]  Czech Mycology 73(1): 91-108   (published: 17th May, 2021)
  abstract   The velamen roots in epiphytic orchids are rather complex, and their environmental role remains poorly understood. Fungal associates are known in the velamen roots of tropical orchids, but the magnitude of their diversity in particular species remains unknown. The primary aim of this work was to explore endophytic fungal species associated with the velamen roots of three tropical epiphytic orchids. Velamen roots were collected from 30 plants of Rhynchostylis retusa and 25 plants each of Epidendrum radicans and Oncidium sphacelatum. Endophytic fungi were isolated from 2160 segments. Twenty species of velamen-root-associated fungal endophytes were separated with a culture technique. The isolated strains were grouped into morphotypes, subsequently identified morphologically and by means of ITS DNA barcoding. Ascomycota were the dominant group with 18 species. Trichoderma cf. asperellum, Endomelanconiopsis endophytica, Trichoderma cf. atroviride and Lasiodiplodia theobromae were the most frequent taxa isolated. A majority of the identified fungi were common to more than one orchid. Colonisation rate, isolation rate, Shannon-Wiener diversity index, species richness and species evenness of the endophytic fungi from different orchids were studied and were tested for significance with the Kruskal-Wallis H test. The colonisation rate and isolation rate of fungal associates in the velamen roots were found to be distinctly the lowest in Rhynchostylis retusa.

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.

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.

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).

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.

NOVÁKOVÁ A., VAUGHAN M.J. (2016): Dimargaris bacillispora - novel records from cave environment and its isolation in culture.   [Dimargitales, cave sediment, cadaver, cave-inhabiting invertebrates, faecal pellets]  Czech Mycology 68(2): 167-182   (published: 7th November, 2016)
  abstract   The coprophilous Dimargaris bacillispora is a rarely found and more rarely isolated microfungal species. In this study, we report the repeated observation and isolation of this fungus from a cave sediment used to rear cave-inhabiting isopods and springtails in the laboratory, originating from the Domica Cave, Slovakia. Dimargaris bacillispora was also observed and isolated from the faeces and cadavers of these laboratory-reared invertebrates. Subsequently, pure culture isolates of D. bacillispora were obtained from these substrates, characterised and identified. Finally, this species was then isolated directly from the cave sediment of the Domica Cave after several days of exposure of agar slants to the cave environment. This is the first record of this species from Europe and from a subterranean environment. Additionally, this study reports a new growth substrate for a fungus which was considered to be strictly coprophilous and mycoparasitic. This study suggests that this species is probably more widely distributed in nature than is reported in the literature, due to the difficulties of viewing its delicate sporophores and growing it in culture.

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.

HOLEC J., KŘÍŽ M., POUZAR Z., ŠANDOVÁ M. (2015): Boubínský prales virgin forest, a Central European refugium of boreal-montane and old-growth forest fungi.   [Mt. Boubín, Bohemian Forest, Czech Republic, Basidiomycota, Ascomycota, diversity, ecology, distribution]  Czech Mycology 67(2): 157-226   (published: 10th September, 2015)
  abstract   Boubínský prales virgin forest is the best-preserved montane Picea-Fagus-Abies forest in the Czech Republic. Its core area (46.67 ha), grown with original montane forest never cut nor managed by foresters, has been protected since 1858. It represents the centre of the present-day nature reserve (685.87 ha). A detailed inventory of its fungal diversity was carried out in 2013–2014. Ten segments differing in habitat and naturalness were studied (235 ha). The total number of species was 659, with the centre of diversity in the core area (503 species) followed by the neighbouring segments grown by natural forests minimally influenced by man. When literature and herbarium data are added, the total diversity reaches a total of 792 taxa. The locality represents a unique refugium for some borealmontane fungi (e.g. Amylocystis lapponica, Laurilia sulcata, Pholiota subochracea), a high number of rare species preferring old-growth forests (Antrodia crassa, A. sitchensis, Baeospora myriadophylla, Chrysomphalina chrysophylla, Fomitopsis rosea, Ionomidotis irregularis, Junghuhnia collabens, Skeletocutis odora, S. stellae, Tatraea dumbirensis), wood-inhabiting and mycorrhizal fungi confined to Abies (Panellus violaceofulvus, Phellinus pouzarii, Pseudoplectania melaena, Lactarius albocarneus), and a high number of indicators of well-preserved Fagus forests (e.g.Climacodon septentrionalis, Flammulaster limulatus, Pholiota squarrosoides). Several very rare fungi are present, e.g. Chromosera cyanophylla, Cystoderma subvinaceum and Pseudorhizina sphaerospora. The value of the local mycobiota is further emphasised by the high number of protected and Red List species. Comparison with other Central European old-growth forests has confirmed that Boubínský prales is a mycological hotspot of European importance.

ABDEL-HAFEZ S.I.I., ABO-ELYOUSR K.A.M., ABDEL-RAHIM I.R. (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.

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.

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.

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 %).

  abstract   In the period 2001-2004, several hundreds of undergroundshelters (mainlyab and onedgalleries, caves, and cellars)inW and SWBohemia(CzechRepublic) were explored for insectcadavers with visi­ blefungalgrowth. At27localities, 94infectedcadavers of sixinsecttaxa were collected.Themostfre­ quentinfectedinsects were 7Yiphosadubitata, Scoliopteryxlibatrix(Lepidoptera;Geometridae and Noctuidae, resp.) and unidentifedmosquitoes(Diptera, Culicidae). On the collectedcadavers, alto­ ge the r20 species of microfungi(includingsterilemycelia) were recorded, most of them belonging to entomopathogens. The most frequent was Paecilomyces farinosus (36 % of all samples) and Cordycepssp.(15%)whichhadaffinitytoC. tuberculata and C.riverae. Closeassociation with insects was shownbyCordycepssp.( with Triphosadubitata) and Conidiobolusdestruens( with unidentified mosquitoes). On the contrary, Paecilomycesfarinosus was recordedonfivedifferentinsect species . Also several other interesting species were found (e.g. Hirsutella guignardii, Engyodontium cf. parvisporum), probably not yet recorded from the Czech Republic. Microphotographs of some microfungi studied are included.

NOVOTNÝ D., JANKOVSKÝ L. (2005): Notes on mycobiota associated with Ips typographus from the Šumava Mts. (Czech Republic).   [Piceaabies, ophiostomatoidfungi, bark beetles]  Czech Mycology 57(1-2): 91-96   (published: 31st August, 2005)
  abstract   In 1999 and 2000, stem samples of Norway spruce (Picea abies) infested by bark beetle (Ips typographus) from one spruce stand localitya ffected by massive infestation by Ips typographus in the central part of the Šumava mountains were taken.The mycobiota of 20 adults was studied. Eighteen species of microscopic fungi were recorded. Yeasts and ophiostomatoid fungi were detected most frequently.

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.

  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   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 %.

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.

NIKOLCHEVA L.G., BÄRLOCHER F. (2002): Phylogeny of Tetracladium based on 18S rDNA.   [Tetracladium, 18S rDNA, Leotiales, Erysiphales, Onygenales]  Czech Mycology 53(4): 285-295   (published: 3rd October, 2002)
  abstract   Complete sequences of 18S rDNA of seven strains of Tetracladium were determined. The following species were included: T. apiense, T. furcatum, T. maxilliforme, T. setigerum (one strain each) and T. marchalianum (3 strains). Sequence homology among the 7 strains was >98%. The closest published match (NCBI database) to the Telracladium sequences is one by Bulgaria inquinans (homology 95-96%). Phylogenetic analysis placed the Tetracladium complex in the vicinity of the Ascomycete orders Onygenales, Erysiphales and Leotiales.

NOVOTNÝ D. (2002): Contribution to the knowledge of the mycoflora in roots of oaks with and without tracheomycotic symptoms.   [Quercus robur, Q. petraea, Q. rubra, oak decline, ophiostomatoid fungi, Penicillium, Czech Republic, Moravia]  Czech Mycology 53(3): 211-222   (published: 10th January, 2002)
  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.

MOSTAFA M.E., ZOHRI A.A., KOTBY R.S. (2001): Lipid, sterol and ergosterol accumulation in isolates of dematiaceous Hyphomycetes.   [Lipid, sterol, ergosterol, dematiaceous hyphomycetes]  Czech Mycology 53(2): 149-159   (published: 20th February, 2002)
  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.

(2000): Root mycoflora of pepper (Capsicum annuum) antagonistic to Verticillium dahliae.   [Frequency of root fungi, Verticillium dahliae, Chaetomium globosum, Gliocladium roseum, Myrothecium verrucaria, Trichoderma harzianum, pepper seed germination]  Czech Mycology 52(3): 219-226   (published: 7th December, 2000)
  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   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   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.

FASSATIOVÁ O. (1995): Micromycetes in archives and book depositories in the Czech Republic.   [Micromycetes, archives, allergies, Czech Republic]  Czech Mycology 48(1): 77-86   (published: 16th May, 1995)
  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.

KAUFMAN L. (1995): Merits and limitations of immunodiagnostic assays for systemic mycoses.   [Systemic mycoses, immunodiagnostic tests, aspergillosis, blastomycosis, candidiasis, histoplasmosis]  Czech Mycology 48(1): 21-29   (published: 16th May, 1995)
  abstract   The incidence of systemic fungal diseases has increased significantly over the last decade. During that time considerable work has been done on isolating and characterizing new antigens and developing technology. However, few new immunodiagnostic tests for the mycoses have come into routine use. Most of the currently used immunodiagnostic tests are designed to detect antibodies to specific fungal pathogens. These tests, though far from optimal, have proved useful for diagnosing aspergillosis, blastomycosis, candidiasis, histoplasmosis and other mycotic infections mainly in the immunocompetent host. They may, however, exhibit cross-reactivity, and fail to distinguish active form past infection, and colonization from invasive disease. More recently, attention has been devoted to developing antigen detection procedures. While such procedures have been successfully developed for cryptococcosis and histoplasmosis, those for the opportunistic mycoses, i.e. aspergillosis and candidiasis have been generally unsatisfactory. Their insensitivity, resulting from the transient nature of the antigen(s) detected or failure to test for a battery of diagnostic antigens. To overcome these problems, current research has focused on the use of more purified antigens, monoclonal or adsorbed polyclonal antibodies, and the refinement or introduction more sensitive assays. An overview of the immunodiagnostic tests currently used, their value and shortcomings will be presented.

(1994): The effect of the heat-stable and chloroform-extractable secondary metabolites of filamentous fungi on the respiratory tract cilia movement of one-day-old chickens in vitro.   [Fungi, cilia, trachea, chickens, metabolites, bronchitis]  Czech Mycology 47(3): 215-221   (published: 17th June, 1994)
  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.

MARVANOVÁ L., KALOUSKOVÁ V., HANULÁKOVÁ D., SCHÁNĚL L. (1993): Misroscopic fungi in the Zbrašov agaronite caves.  Česká Mykologie 46(3-4): 243-250   (published: 25th August, 1993)
  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.

HOLEC J. (1993): Ecology of macrofungi in the beech woods of the Šumava mountains and Šumava foothills.  Česká Mykologie 46(3-4): 163-202   (published: 25th August, 1993)
  abstract   The fungi of the order Agaricales s. l. and several families of ungilled fungi and gasteromycetes were studied in the beech woods of the southeastern part of the Sumava mountains and Sumava foothills (Czechoslovakia). Altogether, 230 species were recorded on 8 permanent plots (50 x 50 m) during the years 1988 - 1990. The terrestrial fungi were closely associated with a particular layer of the surface humus and substrate, and the lignicolous fungi were associated with wood in various stages of decay. The occurrence of mycorrhizal fungi was influenced above all by the mycorrhizal partner, altitude, and climate. The species composition, number of mycorrhizal and terrestrial species on the individual plots, and their share were determined by the humus type, microrelief, and the thickness of the detritus layer. The occurrence of lignicolous fungi was in close relation to the degree of naturalness of the wood, substrate diversity of the plot and the mesoclimate. The results are summarized in the mycosociological tables and compared by the use of cluster analysis and diagrams.

  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   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.

  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.

Besides common soil keratinophilic fungi (e.g., Trichophyton ajelloi, T. terrestre, Microsporum cookei, M. gypseum, Chrysosporium spp.), the dermatophyte Microsporum persicolor was found in 6% of soil and 44.4% of nesting samples, most often in burrows with remains of Clethrionomys glareolus and Apodemus sylvaticus.

STANĚK M. (1984): Microorganisms in the hyphosphere of fungi. I. Introduction.  Česká Mykologie 38(1): 1-10   (published: 10th February, 1984)
  abstract   The surface and immediate surroundings of fungal hyphae affected by their activity is termed the „hyphosphere“. Differences between microorganisms colonizing the hyphosphere and those colonizing a substrate is termed „hyphosphere effect“. The more extensive area of fungal effect on substrate, on the surface and surroundings of fruit-bodies, i.e. the environment affected by the activity of fungi is termed „mycosphere“. The nomenclature proposed is in agreement with the classification of the phytosphere of higher plants. The brief literary survey presents data on incidence of microorganisms in hyphosphere and on their importance, taking into account the results obtained in the Czechoslovak research institutions.

  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.

  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.

  abstract   The following articles should contribute to the knowledge about the representatives of the genus Absidia van Tiegh. in Czechoslovakia and give further precision to some taxonomic problems. The first contribution gives a brief history of the genus, survey of the used material and the available information about species of the genus Absidia from our country, characteristics of the genus, and finally the key for determination of species found in Czechoslovakia.

FRAGNER P., HEJZLAR J., RUBEŠ M. (1979): Otomycoses and mycoflora of otitides.  Česká Mykologie 33(4): 229-236   (published: 1979)
  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.

FASSATIOVÁ O. (1978): Soil micromycetes in abandoned fields in Bohemian Karst.  Česká Mykologie 32(4): 226-234   (published: 1978)
  abstract   An analysis of soil micromycetes in two abandoned fields in the Bohemian Karst during 1976–1977 revealed 64 species in the younger field (7 years) and 50 in the older (50 years). Dominant species in both were: Penicillium albidum, Fusarium solani, Humicola grisea, Absidia cylindrospora, and Mortierella sp. (section Polycephala). The best isolation method used nylon gauze buried in soil.

  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   Downstream of the wastewater outflow from the brewery at Vysoký Chlumec (Bohemia), a considerable growth of fungal filaments occurs year-round. A permanent investigation from April 1970 to February 1971 revealed a stable composition, including Saprochaete saccharophyla, which appeared in large quantities from September 1970 to January 1971. The systematic placement of this organism remains uncertain. It is mostly found in waste and heavily polluted waters and is considered part of their biocenosis.

  abstract   Rhizopus cohnii Berlese et De Toni was microscopically and culturally confirmed in a pig liver. This is, to the authors' knowledge, the first such case in Czechoslovakia and perhaps only the second globally. The pathological, histological, and mycological findings are detailed. The authors support Boedijn’s view that similar species like R. suinus, R. arrhizus, and R. oryzae are conspecific with R. cohnii. The paper also summarizes previous cases of mucormycosis in animals and humans, and compares the isolate with related taxa.

  abstract   A new species of the genus Absidia v. Tiegh., A. macrospora sp. nov., isolated from soil samples is described. It belongs to the group of species of the genus Absidia with globose sporangiospores. It is closely related to the species A. glauca Hagem and A. coerulea Bain., but can easily be distinguished by the size of the sporangiospores and by the shape of the columellae. A key to the species of the genus Absidia with globose sporangiospores is appended.
