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.

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.

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).

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.

KUBÁTOVÁ A., KOUKOL O., NOVÁKOVÁ A. (2011): Geomyces destructans, phenotypic features of some Czech isolates.   [white-nose syndrome, bat disease, Geomyces, Myxotrichaceae, Ascomycota]  Czech Mycology 63(1): 65-75   (published: 10th August, 2011)
  abstract   The microscopic fungus Geomyces destructans is a psychrophilic dermatophyte causing since 2006 a serious bat disease in North America called white-nose syndrome (WNS). In Europe, G. destructans has also been recorded, however less commonly and without striking lethal effects. Currently, seven isolates of G. destructans isolated from greater mouse-eared bat (Myotis myotis) from four localities are maintained in the Culture Collection of Fungi (CCF) in Prague. Growth tests at 12 and 15 °C on eight agar media demonstrated that the fungus grows somewhat faster at 12 °C than at 15 °C. Good growth was observed on nutrient rich media. No further isolates of G. destructans were recovered during screening of bat-associated environments.

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.

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.

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.

NASSER L., ABDEL-SATER M.A. (1997): Fungi associated with sheep hairs in Saudi Arabia.   [Keratinophilic, non-keratinophilic fungi, sheep hairs]  Czech Mycology 50(2): 99-106   (published: 16th December, 1997)
  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.

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.
