NOVOTNÝ D. (2022): Contribution to the endophytic mycobiota of aerial parts of oaks.   [endophytes, Czech Republic, Quercus robur, Quercus petraea, acorns, seeds, twigs.]  Czech Mycology 74(2): 111-121   (published: 1st July, 2022)
  abstract   The endophytic mycobiota inhabiting branches of Quercus petraea from two localities in the Křivoklát area, and branches, twigs and acorns of Quercus robur from one locality near the town of Semily were studied (all sites in the Czech Republic). Seventeen fungal taxa were isolated from branches of Q. petraea. Dominant fungi were found to be Colpoma quercinum and Phoma sp. as well as sterile dark mycelium and a black yeast-like fungus close to Sarcinomyces crustaceus. Eighteen fungal taxa were found in samples of aerial parts in Quercus robur. The most frequently isolated taxa were Pezicula cinnamomea, Colpoma quercinum, Alternaria alternata agg. and Acremonium sp.

SANTIAGO K.A.A., DELA CRUZ T.E.E., TING A.S.Y. (2021): Diversity and bioactivity of endolichenic fungi in Usnea lichens of the Philippines.   [antibacterial, anticandidal, antioxidant, lichen-associated, Sagada.]  Czech Mycology 73(1): 1-19   (published: 14th January, 2021)   Electronic supplement
  abstract   Endolichenic fungi (ELF; asymptomatic microorganisms living inside healthy lichen thalli) were isolated from three Usnea species, namely U. baileyi, U. bismolliuscula and U. pectinata, collected near the town of Sagada, Philippines. A total of 101 ELF were recovered representing 12 genera (classes Sordariomycetes and Eurotiomycetes), with the genera Nemania (50.5%, 51 isolates) and Xylaria (22.8%, 23 isolates) being the most abundant. Comparative analyses on the antimicrobial activities of lichens and ELF revealed that lichen crude extracts were effective against the Gram-positive bacterium Staphylococcus aureus and the yeast Candida albicans, while ELF crude extracts were effective against S. aureus, C. albicans and the Gram-negative bacterium Escherichia coli. The broad-spectrum nature of ELF has provided medicinal and industrial advantages over the slow-growing lichens as shown on their respective bioactivities. Extracts from ELF also had a higher total flavonoid content (TFC; 6.29–85.69 mg QE/g of extract) and stronger antioxidant activities (IC₅₀: 0.57–19.63 mg/ml) than lichen-derived extracts. Although only culturable ELF were identified, this study provides the first evaluation of the diversity and bioactivities of culturable ELF from fruticose lichens of the genus Usnea in the Philippines.

ZÍBAROVÁ L., KOUT J. (2017): Xylariaceous pyrenomycetes from Bohemia: species of Biscogniauxia and Hypoxylon new to the Czech Republic, and notes on other rare species.   [ascomycetes, ecology, lignicolous fungi, Xylariales]  Czech Mycology 69(1): 77-108   (published: 29th June, 2017)
  abstract   Two species of pyrenomycetes, Biscogniauxia mediterranea and Hypoxylon fuscoides, are reported from the Czech Republic for the first time. Descriptions of both species, based on the authors’ collections, are provided together with notes on their distribution and ecology in the Czech Republic and Europe. Additionally new records and short discussions regarding 20 other less common taxa of pyrenomycetes of the genera Biscogniauxia, Euepixylon, Hypoxylon and Nemania (traditionally placed in Xylariaceae) in Bohemia, Czech Republic, are supplied, and recommendations for a future version of the Czech Red list of macromycetes are given.

SAWMYA K., VASUDEVAN T.G., MURALI T.S. (2013): Fungal endophytes from two orchid species - pointer towards organ specificity.   [fungal endophytes, environment, orchids, Bulbophyllum neilgherrense, Pholidota pallida]  Czech Mycology 65(1): 89-101   (published: 10th June, 2013)
  abstract   Fungal endophytes may influence plant communities by altering the host’s fitness either positively or negatively. Little is known, however, about their host/organ specificity, life style and role in plantfungus symbiosis under varying environmental conditions. We compared the leaf and root endophyte assemblages of two orchids (Bulbophyllum neilgherrense and Pholidota pallida) from natural forests and greenhouse conditions. Xylariaceae species were consistently associated with leaf and root tissues, while Guignardia and Pestalotiopsis were found predominantly in the leaf tissues of both orchids. Correspondence analysis of the endophyte assemblages showed that the endophytes exhibited distinct organ but little host specificity. More endophytes were shared by the two different orchids growing in the same location when compared to endophyte assemblages of a single orchid from different locations. Considering the influence of endophytes in shaping the host’s community, diverse habitats must be screened vigorously to address questions regarding the role of endophytes in hostendophyte interactions.

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.

SEIFERT K.A., GAMS W., LOUIS-SEIZE G. (2002): Arthroxylaria elegans, a new coprophilous anamorphic fungus allied with the Xylariaceae, with the notes on the genus Bisporostilbella.   [anamorph taxonomy, coprophilous fungi, hyphomycetes, biodiversity]  Czech Mycology 53(4): 297-307   (published: 3rd October, 2002)
  abstract   The new genus and species Arthroxylaria elegans is described for a synnematous hyphomycete isolated from pack rat dung. The fungus is characterized by the production of tall, lightly pigmented, indeterminate synnemata covered with a layer of unbranched or sparingly branched chains of 0-1-septate meristem arthroconidia. A synanamorph with sympodially-proliferating conidiogenous cells, producing minute aseptate conidia, is also produced. Phylogenetic analyses of partial small subunit ribosomal DNA sequences suggest that the fungus is related to the Xylariaceae, Xylariales, and analysis of internal transcribed spacer sequences places the fungus in Xylaria. The new species is compared with other anamorphs of the Xylariaceae, and a number of similar synnematous and mononematous hyphomycetes, including the poorly understood Bisporostilbella fusca, which is illustrated based on holotype material.

KUBÁTOVÁ A., ČERNÝ M., NOVÁKOVÁ A. (2002): New records of micromycetes from the Czech Republic. IV. 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.

JESENSKÁ Z., PIECKOVÁ E. (1995): Heat-resistant fungi.   [Heat resistance, fungi]  Czech Mycology 48(1): 73-76   (published: 16th May, 1995)
  abstract   The survival of fungi from soil samples has been investigated after temperature of 60, 70, 80 and 90"C in Sabouraud agar. The number of isolated propagules and species had significantly different quantities. The heat-resistant fungi are an economically and scientifically important group of fungi and represent a matter for further investigation.

JESENSKÁ Z., PIECKOVÁ E., BERNÁT D. (1993): Relationships of heat resistant micromycetes from soil to sucrose, natrium chloride and pH.  Česká Mykologie 46(3-4): 263-271   (published: 25th August, 1993)
  abstract   Numbers of colonies of micromycetes, which had been isolated from three soil samples, exposed to 80 'C heat for 60 minutes in Sabouraud agar, were counted. The pH of the agar varied (from 4 to 8), and sucrose (10-50 %), or natrium chloride (2-8 %) were incorporated in the agar. The most resistant germs in the experiment seemed to be the ones of Talaromyces avellaneus (Thom & Turesson) C. R. Benjamin which were present in the soil. The germs of Eupenlcillium baamense (van Beyma) Stolk & Scott were relatively equally sensitive to the experimental conditions as the germs of the Neosartorya físcheri (Wehmer) Malloch & Cain.

PRÁŠIL K., ŠAŠEK V., URBAN Z. (1973): Isolation and cultivation of some stromatic lignicolous Pyrenomycetes. I. Xylariales.  Česká Mykologie 27(3): 133-150   (published: 1973)
  abstract   Twelve species of the order Xylariales were studied in pure culture. Their morphology during growth and the effect of temperature on growth rates were observed. Conidial stages were recorded in ten species, three of them for the first time in culture. The study emphasizes the usefulness of culture studies in clarifying life cycles and taxonomy of stromatic Pyrenomycetes.
