… as displayed at Oct. 12, 2008 OMS Fall Mushroom Show.

Had considered R. cyanoxantha

I had considered it (along with other Russulas). I rejected it (perhaps too soon!) because of the rather uniform olive-drab coloration without much color variation nor with much forking of the gills, which Aurora seems to think important. I honestly can’t say. It is similar to an olive-drab Russula exhibited at the OMS Show yesterday, but seems to me larger than those. That shouldn’t exclude it, but it is not an exact match, either.

Did you consider/eliminate Russula cyanoxantha?
