Amanita porphyria does appear to have a circumpolar distribution. For example, European and North American collections have the same sequence for the “proposed fungal barcode” gene.

Something like the reverse is true for the species that have been called “Amanita rubescens.” There are multiple species that people call by that name in North America and in other parts of the Northern Hemisphere. Many, many species. Of these, only once can be the true European rubescens. All the North American species are different from the European species. So in the case of our various rubescent taxa, none of them occurs in Europe (except possibly by transplant in a tree plantation).

Very best,

Rod

Thank you, for the helpful information! That’s interesting this species could possibly be from Europe.

Good morning, Kat.

I think this is an oldish example of one of the rubescent taxa from eastern North America.

You might like to look at this partial description of porphyria:
