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.
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).
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.
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. (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.
