Mark record


An uncommon, small, orange-capped Lactarius Pers. with white latex was confirmed, using molecular studies of the type specimens, to be Lactarius splendens Hesler & A.H. Sm. Phylogenetic analysis revealed that the species falls within Lactarius section Deliciosi (Fr.) Redeuilh, Verbeken & Walleyn., very closely related to L. rubrilacteus Hesler & A.H. Sm. and L. porninsis Rolland. Hitherto L. porninsis was the only white-latex species known in the otherwise orange-latex section Deliciosi; both are associated with Larix Mill.
