New Species and Records of from Karst Landscapes in Yunnan Province, China.

is a genera-rich and highly diverse family of fungi with a worldwide distribution in aquatic and terrestrial habitats. During the investigation of lignicolous freshwater fungi from karst landscapes in Yunnan Province, China, 15 fresh strains were obtained from submerged decaying wood. Based on the morphology and phylogenetic analysis of a combined LSU, ITS, SSU, and 2 sequence dataset, , , , , and were introduced as new species, and were reported as new habitat records, and and were reported as new collections. In addition, based on morphological comparisons and phylogenetic analysis, we accepted into in the family (, ). Freshwater habitats are the primary habitats of species, and Yunnan Province has the highest concentration and species diversity of in China.
