to rule out porphyria is to see that the UV patches on the caps are white. For porphyria, when such deposits are present they should be gray (and usually not as many patches).

It is remarkable that you could see the UV structure/color from my photo. I don’t have a collection for this MO observation and I cannot send it to you for your examination. Never mind, this specimen looked about the same to us as any other mushroom that we would call “Amanita pantherina”.

Morphology doesn’t support A. porphyria

These mushrooms look like they belong to sect. Amanita. The UV structure/color on the cap and stem base ornamentation are not what one would expect to see for A porphyria. Did this mushroom have a soft, marginate, abrupt and globose bulb?
