Russula jilinensis sp nov (Russulaceae) from northeast China

Russula jilinensis (subg. Coccinula sect. Laetinae), is described from Changbai Mountains, northeast China. The new species is distinguished by its bright red glabrous pileus with a cinnamon tinged disc, slightly yellowish context, dark yellow to ocher spore print, and pileipellis with septate pileocystidia. The morphological characteristics are illustrated in detail and compared with those of similar species. Identification of R. jilinensis was supported by the molecular phylogenetic analysis based on the ribosomal DNA internal transcribed spacer regions (ITS).
