Abstract

Previous phylogenetic analyses have shown the polyphyletic status of the traditional genus Lepista. The concept of Lepista sensu stricto is restricted to the monophyletic clade containing the type species L. densifolia, whose members are highly regarded as important edible mushrooms and valuable germplasm resources. The species diversity of Lepista s.str. in China, however, remains largely unexplored. By conducting phylogenetic analyses based on nucleotide sequences of ITS and six loci (ITS, LSU, TEF1, RPB1, RPB2, and ATP6), we identify a new species and a newly recorded species belonging to Lepista s.str., namely, L. cremeoinvoluta and L. multiformis from Southwestern China. Scanning electron microscopy shows that the basidiospores of L. cremeoinvoluta exhibit distinct verrucose-papillate surfaces, whereas those of L. multiformis display extremely low dimpled warts.
