Abstract: The new species Cortinarius mapuveronicae from Andean-Patagonian Nothofagus-forests is described in a polythetic approach combining chemical analysis of the anthraquinonoid secondary metabolites, microscopical and morphological characteristics, as well as molecular phylogeny. C. mapuveronicae exhibits an intense red color reaction of the basidiomata by treatment with KOH, whereas the basidiospores are turning purplish brown. As responsible compound, the new anthraquinonoid pigment clavorubin-8-O-methylether (1), together with the known monomeric and dimeric anthraquinones (+)-7,7-emodinphyscion (2), emodin (3), emodin-6,8-di-O-methylether (4), questin (5), (+)-(S)-skyrin (6), (+)-(S)-aurantioskyrin (7), hypericin (8), dermolutein (9), and endocrocin (10) could be identified, showing also remarkable activity in a (photo)antimicrobial and (photo)cytotoxic assay. Phylogenetic analysis (ITS, LSU, rpb1) demonstrates a sister group relationship with the holotype of C. rubrobasalis.
