MushroomExpert.com summarizes this species' taxonomy as follows: "Russula virescens, it turns out, is strictly a European species; in North America 'the virescens-crustosa group is much more complex than suspected and embraces at least a dozen taxa in the eastern US' (Buyck & collaborators, 2006). Most of these DNA-defined species have yet to be published, but Russula parvovirescens, with its blue-green colors and very large patches, is one that can be fairly easily recognized without a sequencing laboratory. As for the rest, we have no choice but to call them Russula virescens and Russula crustosa for now, while we await further publications."
