Abstract

The genus Allodiatrype (Diatrypaceae, Xylariales) is reported for the first time collected in Taiyang River National Forest Park, Yunnan Province. An undescribed Allodiatrype species is described and illustrated as a new species based on a combination of morphological characteristics and sequences data of ITS, SSU and TUB2. The new species is characterized by its Y-shaped or cruciate-shaped ostiolar surface, yellowish-green to the green inner layer, and hyaline, ellipsoidal to cylindrical or elongate-allantoid ascospores. The differences between the new species and the related fungi are discussed.
