Lichen and fungal ecology

A new species, Russula nigrovirens, with phenotypic similarities to R. virescens is proposed based on morphological and molecular data. Morphologically, R. nigrovirens is characterized by the combination of non-striate pileus with dull green patches, incurved margin, non-discolouring context, globose to subellipsoid basidiospores with bluntly conical to subcylindrical warts isolated or connected with irregular lines or ridges, and large, clavate basidia. Russula nigrovirens is placed in subgenus Heterophyllidia, subsection Cyanoxanthinae.
