By Michael Kuo:

The traditional concept of Russula virescens calls for a beautiful green russula with a quilted pattern on its cap surface, found under chestnuts and other hardwoods in Europe (the species was originally named in Germany) and North America. However, if you have paid much attention to what’s going on in the world of mushroom taxonomy these days, you will probably not be surprised to hear that the traditional concept turns out to be pretty inaccurate.

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.

I’ve not examined this microscopically & lack the specimen so final
determination is uncertain, but the macro characteristics are suggestive.

How about………….?
