KUBÁTOVÁ A., HUBKA V. (2021): Records of the rare and extremely osmophilic fungi Penicillium eremophilum and Xerochrysium dermatitidis on soy bars. [food-borne fungi, food spoilage, Eurotiomycetes, Eurotiales, Aspergillaceae, xerophiles.] Czech Mycology 73(2): 185-198 (published: 3rd November, 2021)
abstract
The strongly osmophilic and slowly growing fungi Penicillium eremophilum and Xerochrysium dermatitidis were found on soy protein bars. These fungi are worldwide rarely recorded and have been recorded in the Czech Republic for the first time. Penicillium eremophilum is exceptional in the genus Penicillium by the production of 2-spored asci and by the absence of a conidial state. Xerochrysium dermatitidis is predominantly known from food, but some affinity to clinical material has also been recorded. The identification of the strains was confirmed by DNA sequencing. Their macroscopic and microscopic descriptions with photographs completed with known literature data are given.

abstract
Triadelphia (Ascomycota, Microascales) is a genus encompassing pleomorphic dematiaceous micromycetes occurring sporadically on rotting wood and other plant material, infrequently also on other substrates. In this study, we document a second record of Triadelphia morgoensis, found on a twig of Populus nigra near Prague (Czech Republic), after its original description from decaying wood in Hungary. This fungus is characterised by the production of three types of conidia. The identification was achieved by a combination of morphological, physiological and genetic traits. The description of the fungus is emended, and its differentiation from similar species is discussed. Multigene phylogeny showed that T. morgoensis is most closely related to T. loudetiae and T. heterospora. The DNA data from three loci generated in this study (ITS, LSU, RPB2) will facilitate identification of the species in the future. Our results add to the knowledge on the ecology and phylogeny of this understudied fungus, for which neither living type material nor a molecular sequence has been preserved.
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.
KOUKOL O., KUBÁTOVÁ A. (2015): New European records of basidiomycete Burgoa anomala from coniferous litter and sediment in underground tunnel. [ecophysiology, anamorphic Agaricomycotina, Cantharellales, Sistotrema] Czech Mycology 67(2): 241-247 (published: 6th November, 2015)
abstract
Burgoa anomala is a peculiar microscopic basidiomycete not forming any basidiocarps in its life cycle, but producing conspicuous multicellular structures (bulbils) and clamp connections on its mycelium. So far, this saprotroph has sporadically been found mainly on different woody substrates but the overall knowledge of its ecology and distribution is yet sparse due to its rarity. Our records from pine needle litter and sediment in an underground tunnel are only the second and third finds in Europe and the first from these habitats. The identification of this fungus was based on a combination of phenotypic and molecular (ITS rDNA sequence) data. Morphological characteristics and data on its growth between 5–30 °C on selected agar media are presented and discussed.

abstract
Trichoderma fassatiae sp. nov. isolated from forest soil in the Czech Republic is described based on phenotype and DNA sequence data (ITS rDNA, RPB2, and TEF1α). It belongs to the Semiorbis clade in the section Pachybasium. Characters distinguishing it from similar species are provided.
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.
OSTRÝ V., ŠKARKOVÁ J., PROCHÁZKOVÁ I., KUBÁTOVÁ A., MALÍŘ F., RUPRICH J. (2007): Mycobiota of Czech wine grapes and occurrence of ochratoxin A and Alternaria mycotoxins in fresh grape juice, must and wine. [mycobiota, grapes, grape juice, wine, ochratoxin A, Alternaria mycotoxins, HPTLC] Czech Mycology 59(2): 241-254 (published: 28th December, 2007)
abstract
The aim of this study was to monitor the mycobiota of wine grapes, occurrence of ochratoxigenic microfungi in wine grapes and occurrence of ochratoxin A and Alternaria mycotoxins in fresh grape juice, must and wine from domestic crops in the year 2004. Thirteen samples of wine grapes (white /nine samples/ and red /four samples/) were collected during harvesting in the Znojmo wine region, SE Moravia. One sample of a wine grape variety was represented by three subsamples of wine grapes, which were sampled in left, middle and right part of the vineyard. Five wine grape berries per bunch were randomly selected, plated onto Dichloran Rose Bengal Chloramphenicol (DRBC) agar, and incubated for 5–7 days at 25 °C. Alternaria alternata, Cladosporium herbarum, C. cladosporioides, Penicillium expansum, P. aurantiogriseum, P. spinulosum and Rhizopus nigricans were isolated from the samples. Ochratoxigenic microfungi, e. g. Aspergillus carbonarius, and other species of section Nigri, A. ochraceus, Penicillium verrucosum and P. nordicum, were not found in the samples.The HPTLC method for quantification of ochratoxin A (OTA) and Alternaria mycotoxins (alternariol (AOH), alternariol monomethyl ether (AME), altenuene (ALT), and tenuazonic acid (TeA)) in fresh grape juice (13 samples), must (13 samples) and wine (13 samples) was used. The limit of quantification (LoQ) was 8 ng/l for OTA, 1.5 μg/l for AOH, 1.5 μg/l for AME, 1.5 μg/l for ALT and 7.5 μg/l for TeA.Occurrence of OTA and Alternaria mycotoxins in fresh grape juice, must and wine was not proved.

abstract
In the period 2001-2004, several hundreds of undergroundshelters (mainlyab and onedgalleries, caves, and cellars)inW and SWBohemia(CzechRepublic) were explored for insectcadavers with visi blefungalgrowth. At27localities, 94infectedcadavers of sixinsecttaxa were collected.Themostfre quentinfectedinsects were 7Yiphosadubitata, Scoliopteryxlibatrix(Lepidoptera;Geometridae and Noctuidae, resp.) and unidentifedmosquitoes(Diptera, Culicidae). On the collectedcadavers, alto ge the r20 species of microfungi(includingsterilemycelia) were recorded, most of them belonging to entomopathogens. The most frequent was Paecilomyces farinosus (36 % of all samples) and Cordycepssp.(15%)whichhadaffinitytoC. tuberculata and C.riverae. Closeassociation with insects was shownbyCordycepssp.( with Triphosadubitata) and Conidiobolusdestruens( with unidentified mosquitoes). On the contrary, Paecilomycesfarinosus was recordedonfivedifferentinsect species . Also several other interesting species were found (e.g. Hirsutella guignardii, Engyodontium cf. parvisporum), probably not yet recorded from the Czech Republic. Microphotographs of some microfungi studied are included.

abstract
The quality of various types of tea from shops in Prague (Czech Republic) in respect to microfungal contamination was investigated. AlL together, 40samples of tea were tested including black, green and herbal teas. Eighty-one species of microfungi were detected. Aspergillus niger agg. was found to be the most frequent. Great differences were recorded in microfungal species composition between various kinds of tea. However, when using the Monte Carlo Permutation test in CCA, we did not find any correlation between microfungi and type of tea. Aflatoxin production was not proven in any of the tested strains. Colony forming units (CFU) did not exceed the limits valid in the Czech Republic.

abstract
The oak bark beetle (Scolytus intricatus, Scolytidae, Coleoptera) was studied during the years 1997-2003 with respect to the occurrence of microscopic fungi on the surface of its body. Samples were collected in eight localities in the Czech and Slovak Republics. The investigation was focused on all different stages of the beetle’s life cycle: eggs, larvae, adults be for e emergence, adults in generation and maturation feeding (nearly 600 samples), and also on galleries (400 samples). The most frequent fungi associated with S. intricatus were yeasts, Geosmithia spp. and Penicillium spp. Ophiostomatoid fungi were isolated, too. Great attention was paid to the occurrence of Geosmithia spp., which were so far recorded rarely. They were frequently found in all stages of the life cycle of Scolytus intricatus, except for males in maturation feeding. The ecology of Geosmithia spp. in feedings of phloem inhabiting insects is discussed for their negative cellulase production and the ecology of associated insect species. Trees infested with Scolytus intricatus represent a major and still little explored niche of Geosmithia spp.

Acrodontium salmoneum, Chaunopycnis alba and Cylindrocarpostylus gregarius, and notes on Dactylaria lanosa and Trichoderma saturnisporum. [conidial fungi, saprotrophs, biologically active metabolites, Bohemia] Czech Mycology 53(3): 237-255 (published: 10th January, 2002)
abstract
Five saprotrophic mitotic microfungi, Acrodontium salmoneum, Chaunopycnis alba, Cylindrocarpostylus gregarius, Dactylaria lanosa, and Trichoderma saturnisporum, were found during studies of micromycete diversity in the Šumava Mts., Krkonoše Mts., Krušné hory Mts., Prague and Jevany near Prague in the Czech Republic. The microfungi were isolated from soil, except Cylindrocarpostylus gregarius, which was found on bark, and Acrodontium salmoneum isolated from air, seeds and mites. Three of them had not yet been reported from the Czech Republic and are considered to be the first records for this country. Descriptions and illustrations are given. All the fungi are maintained in the Culture Collection of Fungi (CCF), Department of Botany, Faculty of Science, Charles University, Prague.
KUBÁTOVÁ A., NOVOTNÝ D., PRÁŠIL K., MRÁČEK Z. (2000): The nematophagous hyphomycete Esteya vermicola found in the Czech Republic. [conidial fungi, Esteya vermicola, Bursaphelenchus eremus, Scolytus intricatus, nematodes, bark beetles] Czech Mycology 52(3): 227-235 (published: 7th December, 2000)
abstract
During a study of surface mycoflora of the bark beetle Scolytus intricatus (Coleoptera: Scolytidae), the hyphomycetous microfungus Esteya vermicola was found associated with Bursaphelenchus eremus (Nematoda: Aphelenchoididae). Esteya vermicola and Bursaphelenchus eremus were recorded in the Czech Republic for the first time. The find of E. vermicola is considered to be these cond one in the world. Esteya vermicola is a nematophagous species with two types of conidia, described in 1999 from the pinewood nematode Bursaphelenchus xylophilus in Taiwan. Our new records are from the surface of larvae and adult beetles of Scolytus intricatus and their galleries under bark of branches of three species of oak (Quercuspetraea, Q. polycarpa, and Q. robur) on several localities in the Polabí and Křivoklátsko regions, Czech Republic. A description of morphological features and drawings of the fungus are given. Examined strains are maintained in the Culture Collection of Fungi (CCF), Faculty of Science, Charles University, Prague and Czech Collection of Microorganisms (CCM), Faculty of Science, Masaryk University, Brno.

abstract
Data on the occurrence and inducibility of extracellular β-N-acetylhexosaminidase, α-galactosidase, α- and β-mannosidase and α-L-fucosidase, including inductors, are given for selected Aspergillus, Penicillium and Fusarium strains. These data represent additional information on the strains in the Culture Collection of Fungi, Department of Botany, Charles University, Prague, and in the Culture Collection of the Institute of Microbiology, Prague, Czech Republic, thus extending their usability in biochemistry and biotechnology. With respect to these biochemical data a taxonomic evaluation of the examined strains is presented. Several strains were re identified after biochemical and morphological comparisons with the type strains. The strains of A. niveus CCF 544, A. terreus CCF 76, CCF 869, and CCIM USA were re-identified as A. flavipes, the strain A. oryzae CCF 1301 as A. wentii.
