New Contributions on Species Diversity of Genus Hydnum and Lentaria s.l. in China

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 <i>Hydnum</i> and <i>Lentaria</i> sensu lato, most of which were obtained in Yunnan Province. Through ITS-nrLSU-<i>tef1</i> phylogenetic analysis, combined with morphological studies and geographic analyses, five new species were described, viz. <i>H. cremeum</i> (), <i>H. flavoquamosum</i> (), <i>H. roseoalbum</i> (), <i>H. roseotangerinum</i> (), and <i>L. subalpina</i> (). 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, <i>H. flabellatum</i> and <i>H. pallidomarginatum</i>, treating <i>H. flabellatum</i> as a synonym of <i>H. pallidomarginatum</i>. Additionally, a key to <i>Lentaria</i> s.l. in China was provided.
