Lignicolous freshwater fungi are those that grow on submerged woody debris in freshwater streams,ponds, lakes, tree hollows, peat swamps and dams. They play an important role in nutrient and carbon cycling,biological diversity and ecosystem functioning of freshwater ecosystems with their ability to decompose lignocellulose in woody litter, softening the wood and releasing nutrients. The lignicolous freshwater fungi are highly diverse in the classes Dothideomycetes and *** is a class of bitunicate fungi which historically been called the Loculoascomycetes and is currently considered to be the largest and most phylogenetically diverse group within Ascomycota. Species of freshwater Dothideomycetes were among the first ascomycetes to be reported from freshwater *** Dothideomycetes are thought to play an important role in decomposing the submerged woody debris in freshwater ecosystem. In this study, 125 samples were collected from freshwater habitats in China and Thailand. Sixty-nine specimens were identified to 37 species in Dothideomycetes based on evidence from DNA sequence data and morphology, four new genera and 25 new species were introduced. Descriptions, illustrations and phylogenetic tree for these species were *** is one of the largest classes of Ascomycota that comprises a highly diverse range of fungi mainly characterized by perithecial ascomata and inoperculate unitunicate asci. Freshwater Sordariomycetes play an important role in ecosystems and many of them have shown potential values in application. Based on evidence from DNA sequence data and morphology, we introduce a new order, two new families, three new genera, 45 new species, two new combinations and 14 new records. A comprehensive classification of the freshwater Sordariomycetes is outlined based on literature. A modified backbone tree based on combined LSU, SSU, rpb2 and tef1α sequences data of species of freshwater Sordariomycetes is
