Abstract

Laccaria is a large genus within the family Hydnangiaceae, and many potential species remain to be discovered in China. The present study describes three new species, L. carminostipes, L. mangshanensis and L. sinolateritia, and reports two new records, L. japonica and L. versiforma, which 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 the three new species each formed a distinct clade, clearly separated from other known Laccaria species. A detailed description and illustrations of these species are also provided.
