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.

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).

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., 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. (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.

ŠIMONOVIČOVÁ A. (2001): Supplement to the Checklist of non-vascular and vascular plants of Slovakia. The species of microscopic fungi of the order Eurotiales.   [new records of microscopic fungi (Eurotiales), Checklist of non-vascular and vascular plants of Slovakia]  Czech Mycology 53(2): 173-188   (published: 20th February, 2002)
  abstract   Submited are 50 species of microscopic fungi of the order Eurotiales, which are not listed in the Checklist of non-vascular and vascular plants of Slovakia, part Fungi (Lizoň and Bacigálová 1998). The first group is presented by those microscopic fungi which were isolated only once so far. So we consider them to be scarce or rare. From among 30 species of microscopic fungi more than a halfbelongs to the genus Penicillium (16 species ) or genus Aspergillus (6 species ). The genera Eupenicillium, Eurotium and Paecilomyces have two new species, Emericella and Merimbla only one species. The second group is presented by more frequently isolated species of microscopic fungi. From among 20 species the genus Penicillium dominates with 8 species, followed by the genus Aspergillus with 4 species. Other genera(Byssochlamys, Dichotomomyces, Eupenicillium, Eurotium, Fennellia, Paecilomyces and Talarornyces) are presented with one or two species. From the total number of 50 species of microscopic fungi the prevailing part was isolated from different soils (73.3-75.0 %), from different food stuffs (3.3-30.0 %) and from other sources (23.3-45.0 %), including drinking water, dwellings and different materials in depositories and archives.

GHERBAWY Y.A.M.H., PRILLINGER H. (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.

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, Alternaría, 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 penicillia 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.

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.

  abstract   One new genus, Amicodisca (typified by Dasyscypha brdensis Vel.) and six new species are described: Albotricha lupini, Ciliolarina corcontica, Cystopezizella cupulincola, Hamatocanthoscypha acericola, Hyaloscypha cupularum, and Orbilia ebuli. One new combination (Phaeohelotium terrestre) is proposed.

BETINA V. (1986): Fungi in biotechnology-history, present times, perspectives.  Česká Mykologie 40(2): 65-73   (published: 10th May, 1986)
  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.

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.
