Taxonomic and phylogenetic contributions to Diatrypaceae from southeastern Tibet in China.

ABSTRACT: In this study, we investigated the diversity of diatrypaceous fungi from southeastern Tibet in China. The phylogenetic analyses were carried out based on ITS and β-tubulin sequences of 75 taxa of Diatrypaceae from around the world. Based on a combination of morphological features and molecular evidence, a new genus-Alloeutypa, with three new species-A. milinensis, Diatrype linzhiensis, and Eutypella motuoensis, and a new combination-A. flavovirens, were revealed by the materials in China. Alloeutypa is characterized by stromatal interior olivaceous buff, stromata producing well-developed discrete, and ascospores allantoid, subhyaline. These characteristics separate the new genus from the similar genus Eutypa. Comprehensive morphological desc
