Three new ascomycetous fungi from freshwater habitats in China

During a survey of saprobic fungi in Jiangxi and Zhejiang Province, China, three fungal species were collected from decaying wood samples in freshwater habitats. We selected the internal transcribed spacers (ITS1-5.8S-ITS2), large subunit (28S), small subunit (18S), translation elongation factor-1 alpha (<i>tef1</i>), RNA polymerase Ⅰ subunit (<i>rpb1</i>) genes and RNA polymerase II subunit (<i>rpb2</i>) genes for phylogenetic analyses. Maximum likelihood and Bayesian analyses were performed to clarify the phylogenetic affinities of the species. These species are separated from the other species in respective genera based on dimensions in ascomata, asci, ascospores and DNA sequence data. Newly added species are compared with other similar species, and comprehensive descriptions and micrographs are provided.
