Recognized by sight: Cap colors in illustrations and descriptions of A. porphyria vary a bit from place to place. It will probably be useful to do population studies using molecular tools to see if all the “porphyrias” of the Northern Hemisphere are conspecific. – R

Yes, 52461 has a gray underside to the partial veil. I think that could be called porphyria. The other specimen is rather old. I think it is possible that it also is porphyria. Possible.

A. porphyria is probably the other amanitas that i found that we haven’t named yet? http://mushroomobserver.org/53011?q=1lBZ and http://mushroomobserver.org/52461?q=1lBZ

Thanks

Thank you for the level of detail you provided. The soft bulb that is subabrupt and has a slightly raised margin around the top part plus the GRAY partial veil and the brown pigment on the cap arranged in what appear to be subsurface fibrils radiating from the cap’s center (this patter of pigment makes the cap “virgate”) support Amanita porphyria as a reasonable guess for these photographs. The second photograph provides the most useful detail in a single shot.
