[Ascomycota, Dothideales, ITS, LSU, morphology, physiological characteristics, saprotroph.] Czech Mycology 71(2): 219-229 (published: 19th December, 2019)
abstract
Aureobasidium mangrovei was isolated from plant debris in Muscat, Sultanate of Oman. The isolate was characterised and compared with related species of this genus for its growth, colony morphology, and micromorphology. Molecular analysis of the LSU and ITS rDNA supported final identification of the isolate. Our record is the second find in the world and the first in the Sultanate of Oman. DNA sequences of the isolated strain showed 99% (ITS) and 100% (LSU) similarity, respectively, with the sequences of the type isolates from Iran, as well as similar growth and colony morphology. A complete microscopic characterisation, which was not described for the Iranian strain, was made. The Iranian strains were isolated from saline habitats of the protected Hara forests, while our strain was isolated from the leaves of freshwater habitats. A comparison of growth characteristics of both strains under different conditions is provided.

abstract
43 strains of the genus Aureobasidium were isolated from the surface of ants Formica rufa and ladybirds from 6 areas of the lowlands of Záhorie. They were all identified as Aureobasidium pullulans (de Bary) Arnaud but they showed a great variability within the species. On the basis of this variability strains were tested in the similarity by the numerical method. Two subgroups were determined, which could be considered as ecotypes.
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.

(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., 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.
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).
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.
KOUKOL O. (2011): Early spring mycobiota of pine litter needles. [fungal diversity, fungal communities, microfungi, Pinus sylvestris] Czech Mycology 63(2): 153-161 (published: 10th August, 2011)
abstract
Rise in air temperature accompanied by snow-melting in early spring may affect fungi colonising litter needles. This study dealt with the diversity of communities of culturable microfungi colonising Scots pine litter at localities still covered by snow and after snowmelt. Surface-sterilised needles were cultivated on malt agar under two temperature regimes (8/9 and 15/16 °C) and outgrowing fungi were isolated into pure cultures and identified based on morphology and analysis of ITS and partial 28S rDNA regions. Thirty-one fungal species were isolated in total. Dominant colonisers with a colonisation frequency of over 10 % included Verticicladium trifidum, Ceuthospora pinastri, Sympodiella acicola and an unidentified member of Helotiales. Two basidiomycetes, Marasmius androsaceus and Mycena galopus, were also isolated relatively frequently from needles with snow cover, but under different temperature regimes. This preference for different temperatures reflects different niches that these species occupy in coniferous litter. Species richness was significantly higher on needles cultivated at lower temperatures. Widespread use of room temperature for cultivation of samples even from cold seasons may underestimate fungal diversity.
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.

KOUKOL O. (2009): Geographical distribution of Scleroconidioma sphagnicola in coniferous forests in Europe and Canada. [Ascomycota, Larix decidua, Pinus spp., Picea spp., litter needles] Czech Mycology 61(1): 117-124 (published: 29th September, 2009)
abstract
The distribution of the dematiaceous microfungus Scleroconidioma sphagnicola in coniferous litter in Europe and Canada was assessed using a culture-dependent approach. Needles of various coniferous species were sampled between May and November of 2008. Twenty needles from each sample were cultivated on 2° malt agar after surface sterilisation with 30 % hydrogen peroxide. The formed mycelia were identified based on their morphology. The identifications were further confirmed by analyses of ITS rDNA. S. sphagnicola was recorded at 8 of the 53 sites. The highest abundance of S. sphagnicola was recorded in mountain areas of the Czech Republic. Further records of S. sphagnicola were acquired from the literature and the GenBank database. S. sphagnicola does not seem to be a ubiquitous coloniser of coniferous litter. However, this study showed that this fungus is found in various regions and the data obtained may serve to make an evaluation of the potential spread of S. sphagnicola.
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
The anamorphic fungal species Scleroconidioma sphagnicola was repeatedly isolated from spruce and pine litter needles in Šumava National Park. The morphology of thirteen strains of this fungal species was compared; oxidative enzymes and possible parasitism on Sphagnum in vitro were tested. Our results showed that all of the strains differed from the original description in only one characteristic – microsclerotia lacked conidiogenous cells on their surface. All strains produced laccase and peroxidase, eleven strains produced polyphenol oxidases. Inoculation of Sphagnum species resulted in only negligible colonisation. We suppose that Scleroconidioma sphagnicola in the studied area does not parasite on Sphagnum. This conclusion is supported by the fact that strains of Scleroconidioma sphagnicola were isolated from needles lying among Sphagnum, but no diseased plants were found.Results of our previous experiments with Scleroconidioma sphagnicola dealing with decomposition of spruce litter needles and competition with other fungal species are summarised.
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.
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.
SLÁVIKOVÁ E., VADKERTIOVÁ R. (2003): The occurrence of yeasts in grass-grown soils. [yeast community, totalyeast counts, Slovakia, grass-grown soil] Czech Mycology 54(3-4): 239-247 (published: 23rd May, 2003)
abstract
One hundred and fifty six yeast strains were isolated from 160 grass-grown soil samples collected in four different localities in Bratislava, Slovakia. The collection of soil took place in March, May, August, and October. Cryptococcus laurentii, C. albidus, Cyst of ilobasidium capitatum, Sporobolomyces salmonicolor, and Trichosporon cutaneum were the most frequently isolated species from the samples taken in the unpolluted localities Rusovce and Dúbravka. These species represented 92.1 % of totalyeast counts found in these soil samples. Cryptococcus laurentii, C. albidus, Cystofilobasidium capitatum, Debaryomyces castellii, and Rhodotorula glutinis were the most frequently isolated species from the samples taken in the polluted localities Polianky and Mlýnská Dolina. These species represented 93.3 % of total yeast counts there . Yeast densities ranged from 400 to 80.000CFU/g soil. We found that yeasts occurred unevenly in soils during the year. The lowest average number of yeasts was found in August and the highest one in May.
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.
KHAN M.R., SAHA M.L., ANISUZZAMAN M., SLÁVIKOVÁ E. (2002): Yeasts isolated from the lakes of Dhanmondi and Ramna, Bangladesh. [yeast community, occurrence, lake water, Bangladesh] Czech Mycology 53(3): 223-228 (published: 10th January, 2002)
abstract
The occurrence of yeasts in the water of two lakes located in Dhaka City over a period from September to December 1999 was investigated. The number of yeasts of lake Dhanmondi and Ramna ranged from 9.5X10⁴ to 35X10⁴ and 2.3X10⁴ to 11X10⁴CFU/l, respectively.The isolated yeast strains belonged to 5 species: Saccharomyces cerevisiae, Rhodotorula glutinis, Rhodotorula mucilaginosa, Debaryomyces hansenii var. fabryi and C and ida suecica. The maximum number of yeasts was found to be 3 times higher in the water samples of Dhanmondi lake than that of Ramna lake. The higher number of yeasts was correlated with the temperature of the water and with pH values.
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
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.
SLÁVIKOVÁ E., VADKERTIOVÁ R. (1995): Yeast population in the water of a polluted fish-pond. [Yeast population, polluted fish-pond, Slovakia] Czech Mycology 48(2): 145-154 (published: 25th September, 1995)
abstract
The present paper reports the results of a qualitative and quantitative investigation of yeast populations isolated from the water of one fish-pond near Bratislava. Quite a number of fish have perished from disease in this pond. Eighteen different yeast species with various cell densities were identified from one hundred and fifteen water samples. Aureobasidium, Sporobolomyces, Trichosporon, Candida and Cryptococcus species occurred most frequently. The yeast populations of autumn and summer samples are compared. The total yeast count was 11 times higher in autumn than in summer. The distribution and densities of Trichosporon cutaneum, Geotrichum candidum, and to a certain degree of some species of the genus Candida, indicate the predominance of yeasts typical of a polluted aquatic environment.
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.

abstract
Investigations of yeasts isolated from 126 water samples show the occurrence of 16 different species. Two small fish-ponds were sampled twice, in summer and autumn, respectively. The most prevalent species were Aureobasidium pullulans, Sporobolomyces roseus, Hansenula anomala, Hyphopichia burtonii, Leucosporidium scottii, Bullera alba and Candida sp., mainly Candida krusei. The comparison is noted between the yeast population of autumn and summer samples. The total yeast count was 2.5 times higher in autumn than in summer. Isolated yeast strains are characterized by some physiological features.

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
The present paper reports the results of qualitative and quantitative investigation of yeast populations in freshwater of the lake in Jakubov, located in the middle of the Lowland of Záhorie. One hundred and twenty-eight samples offered the possibility to isolate seventy-three yeast strains belonging to twelve genera. Representatives of the genera Candida, Hansenula, Aureobasidium and Rhodotorula occurred most frequently. The occurrence of yeast species at the beginning of the season was twice as heterogeneous as after it. Isolated yeast strains are characterized by some physiological features.

In the years 1975–1980, the occurrence of three species of fungi of the genus Drechslera Ito and one species of Dendryphion Wallroth was found on flax plants (Linum usitatissimum L.) in Czechoslovakia. Two of the reported species had not previously been detected on flax in Czechoslovakia — Drechslera lini (Gentner) Ondřej and Dendryphion nanum (C. G. Nees) Hughes.
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
Yeast and yeast-like microorganisms transferred by ants Formica rufa and ladybirds were isolated from some areas of lowlands of Záhorie. The group of the 21 strains of the yeasts, which were classified to several genera, is described. They were isolated from the surface of ants from some areas of lowlands Záhorie in association with two great genera Debaryomyces and Aureobasidium previously mentioned in our country.

abstract
Fifty-three strains of the genus Debaryomyces were isolated from the surface of Formica rufa ants in nine areas of the Záhorie lowlands. All strains were identified as Debaryomyces cantarellii Capriotti, although they showed high intraspecific variability. Based on numerical taxonomy, two ecotypes were determined. Ants were collected near anthills, and yeast strains were isolated using wort agar. The study also reviews previous work on yeasts from plant material and insects.
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.
