Multi-gene analysis of the crown clade (Russulales, Basidiomycota) revealed six new species and subsect. nov. from Fagaceae forests in China.

Introduction: The crown clade is one of two major groups in the subg. .

Methods/material: An analysis of Chinese samples was performed based on the morphology, internal transcribed spacer (ITS) sequences, and multi-gene phylogenies of 28S nrLSU, 16S mtSSU, , , and .

Four New Species of Subsection from China.

Four new species of subsection from northern and southwestern China under coniferous and deciduous trees are proposed as , , , and . Illustrations and descriptions of , , , and the above four new species are provided based on evidence of morphological characters and phylogenetic analyses of the internal transcribed spacer (ITS), as well as the multi-locus of mtSSU, nLSU, , and -α. The relationships between these new species and allied taxa are discussed.
