I was actually referring to the californian area, but the information was interesting, because I’ve had some problems with our scandinavian “blushers”.
I’ll add a couple of pictures and explain there what I mean..
We do have several blushers in the Americas, with several in North America. Amanita novinupta is the only one that I know of that has been named that occurs in the far western states. Amanita flavorubens is mostly an eastern species, but there is what appears to be a disjunct population in Arizona. Since the latter species occurs in Mexico, the Arizona populations of A. flavorubens probably result from migration along the Sierra Madre Occidental after one or more glaciation events (a GUESS). The most widely collected rubescent taxon in the eastern United States is CALLED “rubescens” in American field guides, but is quite different from the European taxon. I have given it the provisional name of “A. amerirubescens.” Less common in the east and southeast of the US is A. rubescens var. alba Coker. This taxon has at leat pigment and spores shape/size differences from “amerirubescens.”
At least some of the so-called rubescens var. alba of Europe appear to me to be very closely related to A. novinupta. I have seen photographs of the European alba from the Mediterranean and have collected it myself in Norway with Dr. Gro Gulden.
The species A. brunneolocularis (originally described from oak forests in Colombia and Costa Rica) has now been found under pine along a highway in the southeastern U.S. (North Carolina). This is the only known location north of Central America. There are at least two other rubescent taxa known from Mexico that are insufficiently known and have not been named for that reason.
Or do you have several blushers?
