Russula vinosa

Russula vinosa, commonly known as the graying olive brittlegill or darkening brittlegill, is a species of basidiomycete mushroom found in coniferous woodlands across Europe and North America in summer and early autumn. Unlike many red-capped members of the Russula genus, it is edible and mild-tasting. It is usually understood to form a symbiotic relationship with the roots of evergreen trees, though in mountainous areas it has occasionally been found associated with birches instead.
