FASSATIOVÁ O. (1967): Notes on the genus Humicola Traaen. II.  Česká Mykologie 21(2): 78-89   (published: 1967)
  abstract   This continuation of a previous study on the genus Humicola describes two new species: H. minima and H. brunnea, two varieties: H. fuscoatra var. longispora and H. brunnea var. africana, and one new combination. A revised diagnosis of Humicola and a key to the known species are provided.

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.

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.

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 %).

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.

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.

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.

NOVÁKOVÁ-ŘEPOVÁ A., CHALUPSKÝ J. (1993): Microscopic fungi isolated from Fridericia galba (Oligochaeta, Enchytraeidae).  Česká Mykologie 46(3-4): 251-255   (published: 25th August, 1993)
  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.

ŘEPOVÁ A. (1983): Soil micromycetes of forest reserve „Voděradské bučiny“ in Central Bohemia.  Česká Mykologie 37(1): 19-34   (published: 1983)
  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.

VINDUŠKA L. (1979): Fungi in Heterodera schachtii cysts.  Česká Mykologie 33(3): 170-175   (published: 1979)
  abstract   In 1976 and 1977 the occurrence of fungi in Heterodera schachtii Schmidt was determined. From 23.6% of cysts individual fungal species were isolated and determined. In 31.8% of cysts fungi did not occur, from 32.2% cysts bacterial colonies grew and in 12.4% of cysts mixtures of fungi and bacteria were found. From the parasitation point of view, the finding of Verticillium falcatum Petch, Cylindrocarpon destructans (Zinssmeister) Schölten, Humicola grisea Traaen, Fusarium oxysporum Schlecht, emend. Snyder et Hansen and Fusarium solani (Mart.) Appel et Wollenw. is important.

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.

FRAGNER P., HEJZLAR J. (1973): „Graphiosis“- eine neue Erkrankung des Menschen?  Česká Mykologie 27(2): 98-106   (published: 1973)
  abstract   Part of the resting spores of E. virulenta, E. thaxteriana, and E. destruens germinate still after 72 hours of treatment with concentrated ajatin. A culture 14 days old may furnish a viable inoculum after being submerged in concentrated ajatin for 96 hours. The resting spores of all three species are at optimum state in a 14 days old culture, or during the first two months, stored at dry state in the refrigerator (7–15 °C).
