Description
Surveys of Xylariales fungi conducted in southwestern China resulted in the collection of several specimens from Yunnan and Guizhou Provinces. Morphological examination, together with multi-locus phylogenetic analyses based on combined ITS, LSU, rpb2, and tub2 sequence data, revealed that these specimens represent two previously undescribed species within Minuticlypeus and Paravamsapriya. These are introduced here as Minuticlypeus zunyiensis sp. nov. and Paravamsapriya yunnanensis sp. nov. Detailed morphological descriptions, illustrations, and phylogenetic trees clearly delineate these taxa, highlighting their distinct affiliations with existing species.
