Summary:During the investigations of discomycetes in Yunnan, China, five species of were discovered on decayed, decorticated oak trees or unidentified wood. All species have typical disc-like, large fruiting bodies with grey, brown or greyish-green colors. The ITS sequence analysis showed that they belong to (Helotiaceae, Helotiales) and the LSU and ITS combination revealed a different topology within the genus. Four species, , , and were established as new species, and was collected and described on oak woods. The pairwise homoplasy index (PHI) test results indicated that there is no significant genetic recombination (Φ = 1.0) between all related species pairs. All the species described here are supported by descriptions, illustrations and multi-gene analyses.
