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.

ADAMČÍK S., CHRISTENSEN M., HEILMANN-CLAUSEN J., WALLEYN R. (2007): Fungal diversity in the Poloniny National Park with emphasis on indicator species of conservation value of beech forests in Europe.   [wood-inhabiting fungi, indicator species, beech forests, biodiversity, Slovakia, macromycetes]  Czech Mycology 59(1): 67-81   (published: 28th June, 2007)
  abstract   This paper lists recent finds of macrofungi from the Poloniny National Park in Slovakia. The list contains data on the occurrence of 62 taxa of macrofungi, 35 of which are new to Poloniny, and 15 have not previously been recorded from Slovakia. Additionally, 17 rare species generally considered as threatened in large parts of Europe were found. The study increases the number of fungal indicator species proposed for assessment of the conservation value of European beech forests known from selected nature reserves in Poloniny. The results of this study combined with previously published data shows that Stužica and Rožok National Nature Reserves are the sites with the highest number of these indicator species in Europe.

  abstract   A new species of Nemania is described and named in honor of Dr. Z. Pouzar. It resembles N. carbonacea, differing in the shorter ascus stipes, larger ascospores, less fragile and less extensive stromata. Cultures are described. An anamorph is unknown.

POUZAR Z. (1985): Reassessment of the Hypoxylon serpens-complex II.  Česká Mykologie 39(3): 129-134   (published: 13th August, 1985)
  abstract   In this second contribution is newly defined Nemania aenea (Nitsch.) Pouz., which is based on Hypoxylon aeneum Nitsch., a species considered as rather obscure one in present literature. To give a more precise picture of its systematic position in Nemania S. F. Gray em. Pouz., a key is given to all species known in this genus. This contribution is a continuation of the previous work on Nemania (Pouzar 1985).

POUZAR Z. (1985): Reassessment of Hypoxylon serpens - complex I.  Česká Mykologie 39(1): 15-25   (published: 1985)
  abstract   Based on specimens coming mostly from Central Europe, the group of species closely related to Hypoxylon serpens (Pers.: Fr.) J. Kickx fil. is newly classified with emphasis on microscopic characters. The Hypoxylon serpens-complex is separated from Hypoxylon Bull. and classified as a genus of its own, Nemania S. F. Gray in a considerably changed circumscription. Eight species are newly transferred to Nemania. One species is described as new: Nemania carbonacea Pouz. spec. nov. and the problem of N. atropurpurea (Fr.) Pouz. is discussed in detail.

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.

ADAMČÍK S., AUDE E., BÄSSLER C., CHRISTENSEN M., DORT K.VAN, FRITZ Ö., GLEJDURA S., HEILMANN-CLAUSEN J., HOLEC J., JANČOVIČOVÁ S., KUNCA V., LACKOVIČOVÁ A., LÜTH M., ÓDOR P. (2016): Fungi and lichens recorded during the Cryptogam Symposium on Natural Beech Forests, Slovakia 2011.   [old-growth beech forests, diversity, conservation, indicator, red-list, Europe]  Czech Mycology 68(1): 1-40   (published: 1st February, 2016)
  abstract   In September 2011, an international team of cryptogam experts visited seven national nature reserves in five mountain areas of Slovakia: Havešová and Stužica in the Poloniny Mts., Vihorlat in the Vihorlatské vrchy Mts., Oblík in the Slanské vrchy Mts., Dobročský prales and Klenovský Vepor in the Veporské vrchy Mts. and Badínsky prales in the Kremnické vrchy Mts. The reserves were selected to represent examples of the best protected old-growth beech forests in the country. The aim was to study the diversity of wood-inhabiting fungi on fallen beech logs and epiphytic lichens on standing beech trees. In total, 215 fungal species and 128 lichens were recorded on beech wood and bark, and 27 fungi and 26 lichens on additional substrates. The site of the highest conservation value is Stužica with 126 fungi and 79 lichens recorded on beech, of which 12 fungi and 19 lichens are indicators of high nature conservation value. Combined with historical records, a total of 19 non-lichenised fungal indicators are now reported from the site, making it the highest ranked natural beech forest in Europe. The second most important reserve for fungal diversity is Havešová with 121 species, including 14 indicator species recorded on beech wood. For lichens, the second most important reserve is Klenovský Vepor with 69 species including 18 lichen indicators recorded on beech. Nine fungus species are here reported as new to Slovakia: Asterostroma medium, Entoloma hispidulum, E. pseudoparasiticum, Gloeohypochnicium analogum, Hohenbuehelia valesiaca, Hymenochaete ulmicola, Hypocrea parmastoi, Melanomma spiniferum and Scutellinia colensoi. Lichen species Alyxoria ochrocheila is reported as new to Slovakia and Lecanographa amylacea, which was considered extinct in the Slovak Red list, was also recorded. This is the first list of wood-inhabiting fungi and epiphytic lichens of old-growth beech forests in Slovakia, and hence an important contribution to the exploration of biodiversity in Slovakia.

HOLEC J., KŘÍŽ M., POUZAR Z., ŠANDOVÁ M. (2015): Boubínský prales virgin forest, a Central European refugium of boreal-montane and old-growth forest fungi.   [Mt. Boubín, Bohemian Forest, Czech Republic, Basidiomycota, Ascomycota, diversity, ecology, distribution]  Czech Mycology 67(2): 157-226   (published: 10th September, 2015)
  abstract   Boubínský prales virgin forest is the best-preserved montane Picea-Fagus-Abies forest in the Czech Republic. Its core area (46.67 ha), grown with original montane forest never cut nor managed by foresters, has been protected since 1858. It represents the centre of the present-day nature reserve (685.87 ha). A detailed inventory of its fungal diversity was carried out in 2013–2014. Ten segments differing in habitat and naturalness were studied (235 ha). The total number of species was 659, with the centre of diversity in the core area (503 species) followed by the neighbouring segments grown by natural forests minimally influenced by man. When literature and herbarium data are added, the total diversity reaches a total of 792 taxa. The locality represents a unique refugium for some borealmontane fungi (e.g. Amylocystis lapponica, Laurilia sulcata, Pholiota subochracea), a high number of rare species preferring old-growth forests (Antrodia crassa, A. sitchensis, Baeospora myriadophylla, Chrysomphalina chrysophylla, Fomitopsis rosea, Ionomidotis irregularis, Junghuhnia collabens, Skeletocutis odora, S. stellae, Tatraea dumbirensis), wood-inhabiting and mycorrhizal fungi confined to Abies (Panellus violaceofulvus, Phellinus pouzarii, Pseudoplectania melaena, Lactarius albocarneus), and a high number of indicators of well-preserved Fagus forests (e.g.Climacodon septentrionalis, Flammulaster limulatus, Pholiota squarrosoides). Several very rare fungi are present, e.g. Chromosera cyanophylla, Cystoderma subvinaceum and Pseudorhizina sphaerospora. The value of the local mycobiota is further emphasised by the high number of protected and Red List species. Comparison with other Central European old-growth forests has confirmed that Boubínský prales is a mycological hotspot of European importance.

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.

JOHNOVÁ M. (2009): Diversity and ecology of selected lignicolous Ascomycetes in the Bohemian Switzerland National Park (Czech Republic).   [ascomycetes, lignicolous pyrenomycetes, biodiversity, ecology, endangered species]  Czech Mycology 61(1): 81-97   (published: 29th September, 2009)
  abstract   Lignicolous pyrenomycetes, their anamorphs and asexually reproducing Ascomycetes were investigated on deciduous and coniferous wood at 10 localities of the Bohemian Switzerland National Park (České Švýcarsko in Czech) during 2003–2005. A total number of 109 species was recorded, 11 species were found both as teleomorph and anamorph. Individual localities were evaluated from the viewpoint of Ascomycetes diversity. Ecological demands, relationship with the type of substratum, and microhabitat preferences were noted and several ecological groups are suggested. Rare and endangered species and factors affecting Ascomycetes diversity are discussed. Several species new to the Czech Republic were recorded, viz. Apiorhynchostoma altipetum, Camarops pugillus, Crassochaeta fusispora, Lophiotrema boreale, and Togniniella acerosa.

POUZAR Z. (1986): A key and conspectus of Central European species of Biscogniauxia and Obolarina (Pyrenomycetes).  Česká Mykologie 40(1): 1-10   (published: 7th February, 1986)
  abstract   A key is given to all known Central European species of the genus Biscogniauxia O. Kuntze ( = Nummularia L.-R. Tul. et C. Tul.) and the new genus Obolarina Pouz. gen. nov. (type: Nummularia dryophila L.-R. Tul. et C. Tul.). A new species Biscogniauxia querna Pouz. spec. nov. is described from southern Moravia, characterized by broad ascospores with bilateral germination slit.
