Extract from Wikipedia article: Russula parvovirescens is a basidiomycete mushroom of the genus Russula. Found in the eastern United States, it was described as new to science in 2006. It is similar in appearance to the more widespread Russula virescens and R. crustosa, but can be distinguished from those species by its smaller stature, and microscopically by the voluminous terminal cells of the cap cuticle.
