Abstract
lacaria is a large genus within the Hydnangiaceae family, and there are still many potential species to be discovered in China. The present study describes three new species, L. carminostipes, L. mangshanensis and L. sinolatericiaand reports two new records, L. japonica and L. versiformawhich were originally discovered in Japan and Korea, respectively. These species were collected from subtropical mixed forests and identified based on morphological and phylogenetic evidence. Our phylogenetic analysis of the concatenated nucleotide sequences of ITS, LSU, TEF1, and RPB2 demonstrated that each of the three new species formed a distinct clade, clearly separated from other known Laccaria species. A detailed description and illustrations of these species are also provided.
