Four new species of Russulasubsect.Cyanoxanthinae from China (Russulales, Russulaceae).

ABSTRACT: Four new species of Russulasubsect.Cyanoxanthinae, viz. Russulaatrochermesina Y.L. Chen & J.F. Liang, R.lavandula Y.L. Chen, B. Chen & J.F. Liang, R.lilaceofusca Y.L. Chen & J.F. Liang and R.perviridis Y.L. Chen, B. Chen & J.F. Liang, from China are proposed, based on morphological and molecular evidence. Russulaatrochermesina can be distinguished by its violet pileus with tuberculate-striate margin, distant lamellae that stain greyish-yellow when bruised, basidiospores ornamented by isolated warts, wide hymenial cystidia on lamellae edges, cystidia content negative reaction in sulphovanillin and branched subterminal cells in pileipellis. Russulalavandula has a purplish-white to violet red pileus with a yellow centre, frequently present lamellulae
