Diversity and ecology of selected lignicolous Ascomycetes in the Bohemian Switzerland National Park (Czech Republic).

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.
