Three new Russula species in sect. Ingratae (Russulales, Basidiomycota) from southern China

Abstract

Three new species of Russulasection Ingratae, found in Guizhou and Jiangsu Provinces, southern China, are proposed: <i>R.straminella</i>, <i>R.subpectinatoides</i> and <i>R.succinea</i>. Photographs, line drawings and detailed morphological descriptions for these species are provided with comparisons against closely-related taxa. Phylogenetic analysis of the internal transcribed spacer (ITS) region supported the recognition of these specimens as new species. Additionally, <i>R.indocatillus</i> is reported for the first time from China and morphological and phylogenetic data are provided for the Chinese specimens.
