Abstract

Yunnan Province is rich in freshwater resources, providing a favorable environment for freshwater fungi. As a result, numerous new species have been described in recent years, further supporting the extensive diversity of freshwater fungi in this region. During an investigation of lignicolous freshwater fungi from the Dulongjiang River, six fresh isolates of Dictyosporiaceae were obtained. The new collection includes two new species ( Dictyocheirospora splendida and Jalapriya guttulata ), two new records ( D. nabanheensis and Dictyosporium hughesii ), and one known species ( Dictyosporium duliujiangense ). They are introduced based on morphological evidence and molecular phylogenetic analysis of combined ITS, LSU, and tef 1-α sequence data. Detailed descriptions and illustrations of these species are provided, and morphological comparison with similar taxa is discussed.
