Southwest China is extremely rich in fungal resources, and a large number of new taxa have been discovered in recent years. In the present study, we examined 26 specimens of the genera Hydnum and Lentaria sensu lato, most of which were obtained in Yunnan Province. Through ITS-nrLSU-tef1 phylogenetic analysis, combined with morphological studies and geographic analyses, five new species were described, viz. H. cremeum (), H. flavoquamosum (), H. roseoalbum (), H. roseotangerinum (), and L. subalpina (). Furthermore, we also supplied new information on some known species, including host plants and new distribution records. We re-examined the holotype sequences of two known taxa, H. flabellatum and H. pallidomarginatum, treating H. flabellatum as a synonym of H. pallidomarginatum. Additionally, a key to Lentaria s.l. in China was provided.
