Additions to hyphomycetes from Yungui Plateau, China with three new species (Ascomycota, Sordariomycetes)

Abstract

Background Yungui Plateau is rich in fungal diversity. Hyphomycetes, growing on submerged wood, can promote the degradation of organisms and the reuse of rotten wood energy. During an investigation of hyphomycetes in this region, 19 species of dematiaceous hyphomycetes were collected in Yungui Plateau. New information Both morphological identification and multi-gene phylogenetic analyses of ITS, tef1 and LSU sequences supported Coryneum sevenseptatis as a new species. Phaeoisaria guizhouensis and Pleurothecium yunanensis were introduced, based on morphology. Morphological descriptions and illustrations of the new species were detailed. Known species are listed with notes.
