摘要：

During a survey of saprobic fungi on coffee samples in Yunnan Province, China, in 2020 and 2022, fungal fruiting bodies on decaying Liberian coffee twigs were collected and isolated. Maximum likelihood and Bayesian analyses of combined ITS, LSU, and RPB2 genes showed that the two isolated fungal strains belonged to a distinct species in Coniocessiaceae and were well separated from closely related genera with 73% ML and 0.92 PP statistical support. Morphologically, this distinct species can be differentiated from other genera in Coniocessiaceae by aseptate hamathecium, 4-8-spored asci with a flat apical ring, and fusiform ascospores, conical at the lower end. Based on morphology and phylogenetic analyses, the two fungal strains are described as a distinct new genus Pseudoconiocessia, within Coniocessiaceae. Pseudoconiocessia is introduced here with Pseudoconiocessia xishuangbannaensis as the type species.
