FASSATIOVÁ O. (1988): Toxinogenic species of the genus Penicillium Link and a key to the determination of frequently occurring representatives in Bohemia.  Česká Mykologie 42(1): 12-22   (published: 10th February, 1988)
  abstract   A survey of twenty frequently occurring, potentially toxigenic Penicillium Link species and two varieties with data about their toxins and origin of their isolates in Bohemia is submitted. A key to the determination of these taxa with brief descriptions is compiled and complemented by drawings of certain morphological features of the colony and penicillus.

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

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.

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.

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.

ŠIMONOVIČOVÁ A. (1992): Microfungal community structure in forest soils of North Slovakia. II. Similarity of mykocenosis (Krížna, Koprová and Furkotská Vallies).  Česká Mykologie 46(1-2): 106-113   (published: 1st April, 1993)
  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.

ŠIMONOVIČOVÁ A. (1992): Microfungal community structure in forest soil of North Slovakia. I. Similarity of mykocenosis (The Valley Tichá).  Česká Mykologie 46(1-2): 99-105   (published: 1st April, 1993)
  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.

ŘEPOVÁ A. (1989): Soil micromycetes from Czechoslovakia-a list of isolated species with bibliography. III.  Česká Mykologie 44(1): 35-50   (published: 22nd February, 1990)
  abstract   A list of micromycetes (saprophytic, keratinophilic, rhizosphere, nematophagous, ovicidal, dermatophytes, and cellular slime moulds) isolated from various Czechoslovak soils is presented. Records about species distribution in Czechoslovakia and bibliography are included for each micromycete species.

ŘEPOVÁ A. (1986): The occurrence of microscopic fungi in air of the building of the Czechoslovak Acadeny of Sciences in České Budějovice.  Česká Mykologie 40(1): 19-29   (published: 7th February, 1986)
  abstract   68 species of microscopic fungi were isolated from the air in the building of the Czechoslovak Academy of Sciences in České Budějovice. 16 species were opportunistic, 12 allergenic, and 13 mycotoxin producers. 8 species were reported as air-borne fungi in literature.

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.

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