HOLEC J., WILD J. (2011): Fungal diversity in sandstone gorges of the Bohemian Switzerland National Park (Czech Republic): impact of climatic inversion.   [macromycetes, ecology, microclimate, boreal-montane fungi]  Czech Mycology 63(2): 243-263   (published: 10th August, 2011)
  abstract   The diversity of macrofungi in 8 sandstone gorges (narrow valleys bordered by sandstone walls, mostly covered by Picea forests with admixed Fagus, alt. 170–390 m) was assessed with respect to microclimatic data from 235 stations measuring temperature and soil moisture along the elevation gradient. In total, 253 species of macrofungi were found including some boreal-montane species, species preferring moist habitats and/or species of more or less natural vegetation. Microclimatically, the bottoms of gorges are significantly colder than their slopes and slope crests during the vegetation period (climatic inversion) and show higher soil moisture throughout the year. However, they are not significantly colder during the winter period and even show a higher average minimal temperature than the rest of gorges. Generally, bottoms of sandstone gorges function as „buffers“ maintaining a stable, humid and rather cold microclimate and enabling the occurrence of some boreal-montane fungi and species requiring humid conditions. Climatic inversion is a phenomenon markedly influencing the distribution of fungi in the landscape and enabling extrazonal occurrence of some species.

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., 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.

VAŠUTOVÁ M. (2004): Macromycetes of permanent plots in cultural forests in the Moravskoslezské Beskydy Mts. and Vsetínské vrchy hills (Czech Republic).   [Czech Republic, macromycetes, cultural beech and spruce forests, mycocoenology, permanent plots, ecology]  Czech Mycology 56(3-4): 259-289   (published: 22nd December, 2004)
  abstract   The mycoflora of cultural (artificial and managed subnatural) forests (i.e. beech, spruce and mixed forests) was studied in 18 permanent plots in the Moravskoslezské Beskydy Mts. and the adjacent part of the Vsetínské vrchy hills (Czech Republic) during they ears 1998-2000. Al together, 314 species of macromycetes were recorded. The highest number of species was recorded in plots in a young spruce forest on a former meadow (72 species ) and a waterlogged spruce forest (67 species ). Mycorrhizal fungi were the dominant group in older spruce forests (44.2 %), waterlogged spruce forests (43.3 %) and alder forest (45.6 %). A high percentage of terrestrial saprophytes was found in the young forest on a former meadow (43 %). Generally, common species prevailed.The main factor which influenced the species composition of all trophic groups was the composition of the tree layer. These results are compared with results from similar plots in the Czech Republic and neighbouring countries.

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.

MIHÁL I. (1993): Frequency and occurrence stability-method of determination of dominant fungi species in beech wood after cutting operation.  Česká Mykologie 46(3-4): 282-295   (published: 25th August, 1993)
  abstract   The mycoflora of southern part of Kremnica Hills was studied by autor in 1990 and 1991. The dominant species of macromycets of beech forest stand were found out after cutting operation with the aid of frequency and occurence stability of determined fungi species. The autumn mycoaspect was characterized by occurence of these dominant fungi species: Hypoxylon fragiforme, Marasmius alliaceus, Hygrophorus ebumeus, Armiilaria ostoyae and others. The spring mycoaspect was characterized by species: Ustulina deusta, Bispora antennata, Collybia dryophila and others. The spring mycoaspect was speciesly poorer in comparison with the autumn mycoaspect in consequence of unfavourable climatic conditions. The wood-rotting fungi species have prevailed on the area. At the same time the species typical for warm-weather oak forests have been finding on the area together with the species of montane beech woods and fir-beech woods.

KOTLABA F. (1981): Excursio mycologorum Bohemicorum in Karlštejn anno 1980.  Česká Mykologie 35(2): 108-111   (published: 1981)
  abstract   A mycological excursion to Karlštejn in 1980 is reported. Due to dry weather, few fungi were found. A complete list of all observed species is published, including common ones, unlike previous reports that listed only rare taxa.

POUZAR Z. (1972): Hypoxylon fraxinophilum spec. nov. and H. moravicum spec. nov., two interesting species found on Fraxinus angustifolia.  Česká Mykologie 26(3): 129-137   (published: 20th July, 1972)
  abstract   Two species of the genus Hypoxylon Bull. ex Fr. em. J. H. Miller (section Hypoxylon) are reported, found on branches of Fraxinus angustifolia Vahl in South Moravian bottomland forests: Hypoxylon fraxinophilum Pouz. spec. nov., previously known under the illegitimate name (later homonym) Hypoxylon argillaceum (Pers. ex Pollini) Nitschke, and Hypoxylon moravicum Pouz. spec. nov., a species similar to H. rubiginosum (Pers. ex Fr.) Fr., differing in the peculiar development of stromata (stellate in young stages) and the inamyloid apical apparatus of asci.

SVRČEK M., KUBIČKA J. (1964): Fungi from the Žofínský Virgin Forest in the Novohradské mountains (Southern Bohemia).  Česká Mykologie 18(3): 157-179   (published: 14th July, 1964)
  abstract   The authors report on higher fungi of the Žofínský Virgin Forest near Nové Hrady in Southern Bohemia, the oldest forest reserve in Bohemia. Covering 97 ha at 740–830 m elevation, the forest contains mostly Fagus silvatica, Abies alba, and Picea excelsa. During two excursions, 227 species of higher fungi were collected: 131 Agaricales, 67 Aphyllophorales, 17 Discomycetes, 12 Pyrenomycetes, and 10 Myxomycetes. One new species, Collybia terginoides, and one new variety, Paxillus panuoides var. rubrosquamulosus, are described. Three species were reclassified. New species for Bohemia are marked with an asterisk.
