Four New Species of Russula Subsection Sardoninae from China

Abstract

Four new species of <i>Russula</i> subsection <i>Sardoninae</i> from northern and southwestern China under coniferous and deciduous trees are proposed as <i>R. begonia</i>, <i>R. photinia</i>, <i>R. rhodochroa</i>, and <i>R. rufa</i>. Illustrations and descriptions of <i>R. gracillima</i>, <i>R. leucomarginata</i>, <i>R. roseola</i>, 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, <i>rpb1</i>, <i>rpb2</i> and <i>tef1</i>-α. The relationships between these new species and allied taxa are discussed.
