Abstract

The Red River Basin is located in the Indo-Burma biodiversity hotspot and is rich in lignicolous freshwater fungi, but no systematic research has been conducted. A systematic study on the species diversity of lignicolous freshwater fungi in the basin is ongoing. Seven distoseptispora-like specimens were collected from the Red River Basin in Yunnan. Phylogenetic analysis of ITS, LSU, tef1-α, and rpb2 genes and combined morphological data indicate that there are six distinct species of Distoseptispora, including two new species and four known species. Two new species were named D. suae and D. xinpingensis, and the four known species were D. bambusae, D. euseptata, D. obpyriformis and D. pachyconidia. This study provides detailed descriptions and illustrations of these six species and an updated phylogenetic backbone tree of Distoseptispora.
