Russula brevipes is one of the most common Russula species on the west coast, and is easily identified by its stature, large size, and white coloration which does not stain when handled. Russula brevipes var. acrior is distinguished by the greenish discoloration of the gills and conspicuous greenish band around the apex of the stipe.
