During the investigations of discomycetes in Yunnan, China, five species of Tatraea 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 Tatraea (Helotiaceae, Helotiales) and the LSU and ITS combination revealed a different topology within the genus. Four species, T. clepsydriformis , T. griseoturcoisina , T. yunnanensis and T. yuxiensis were established as new species, and T. aseptata was collected and described on oak woods. The pairwise homoplasy index (PHI) test results indicated that there is no significant genetic recombination (Φ w = 1.0) between all related species pairs. All the species described here are supported by descriptions, illustrations and multi-gene analyses.
