摘要：
Nectria tibetensis sp. nov. is described and illustrated based on specimens collected from Nyingchi City, Tibet Autonomous Region, China. The fungus occurs at high altitudes, and is characterized by superficial, aggregated, subglobose to globose ascomata with warted surface, and clavate asci with ellipsoidal to fusiform, 1-septate ascospores that are hyaline and spinulose. The perithecial gross morphology, anatomic structures and asexual morph characteristics indicate that it belongs to Nectria which was confirmed by the combined sequence analyses of act1, ITS, LSU, rpb1, tef1 and tub2 regions. Nectria magnispora and Thyronectria coryli are reported for the first time from China.
