Morphological and Phylogenetic Analyses Reveal Three New Species of Distoseptispora (Distoseptisporaceae, Distoseptisporales) from Yunnan, China

Three new species of Distoseptispora, viz. D. mengsongensis, D. nabanheensis, and D. sinensis, are described and illustrated from specimens collected on dead branches of unidentified plants in Yunnan Province, China. Phylogenetic analyses of LSU, ITS, and TEF1 sequence data, using maximum-likelihood (ML) and Bayesian inference (BI), reveal the taxonomic placement of D. mengsongensis, D. nabanheensis, and D. sinensis within Distoseptispora. Both morphological observations and molecular phylogenetic analyses supported D. mengsongensis, D. nabanheensis, and D. sinensis as three new taxa. To extend our knowledge of the diversity of Distoseptispora-like taxa, a list of recognized species of Distoseptispora with major morphological features, habitat, host, and locality is also provided.
