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.
