Species diversity and taxonomy of Scytinostroma sensu stricto (Russulales, Basidiomycota) with descriptions of four new species from China.

ABSTRACT: Scytinostroma is species-rich genus in Peniophoraceae, Russulales and has been shown to be polyphyletic. In this study, we performed phylogenetic analyses on the core clade of Scytinostroma based on concatenated ITS1-5.8S-ITS2-nrLSU sequence data. Fifteen lineages including four new species from China, Scytinostromabeijingensis, S.boidinii, S.subduriusculum, and S.subrenisporum, were recognized. The genus Michenera was nested within the Scytinostroma s.s. clade in the phylogenetic tree of Peniophoraceae. Sequences of S.portentosum (type species) and S.hemidichophyticum from Europe formed a strongly supported lineage sister to the S.portentosum sample from Canada. It is supposed that the European "S.portentosum<
