Abstract

Saprobic hyphomycetes with high density and species diversity were observed on plant debris. During our mycological surveys in southern China, numerous strains were isolated from dead branches of unidentified plants in the forest of Jiangxi and Fujian provinces, China. Phylogenetic analyses of ITS, LSU, RPB2, and TEF1 sequence data using maximum-likelihood (ML) and Bayesian inference (BI) methods revealed the systematic placement of several Sporidesmium-like species within Distoseptispora. Based on morphological characteristics and molecular evidence, four new species of Distoseptispora, namely D. fujianensis, D. ganzhouensis, D. nanpingensis and D. subtropica, are introduced, and two known species, D. clematidis and D. yunjushanensis, are reported. This study enhances our knowledge of the species diversity of Distoseptispora in southern China.
