摘要：
Two specimens of Hypoxylon were collected from Yunnan, southwestern China. Hypoxylon baihualingense, an =described species of Hypoxylon (Xylariales, Hypoxylaceae), is described and illustrated as a new species based on a combination of morphological and phylogenetic (ITS and beta-tubulin sequences) data. The new species is characterized by its glomerate to pulvinate stromata with ostiolar discs and asci lacking an apical apparatus. The differences between the new species and some morphologically similar Hypoxylon species are discussed. Hypoxylon polyporoideum is reported as a new record from China.
