Abstract
Specimens of three unnamed club-shaped fungi, collected from the Hengduan Mountains region in China, are formally described as Clavariadelphus acuminatus, C. miniatus, and C. pseudoelongatus. Based on ITS, nrLSU, ATP6, and TEF1 sequence data, a multigene phylogenetic analysis indicated that the three new species each formed a distinct lineage within the Clavariadelphus clade with strong support. Descriptions, illustrations, and the results of molecular phylogenetic analyses for the three newly discovered species are presented. A taxonomic key for the known Clavariadelphus species in China is provided.
