Sounds like a good plan.

Very best,


I no longer have the specimen.

but I can safely say there was a bulb on it, The ring was detached, however when I pulled if from the ground it was attached to the stipe, if only by a little. I should have done a cross section…

Interesting observations, Irene.

Does the specimen still exist? I’m thinking that if you cut it down the center lengthwise, you might be able to tell if the base of the stipe is bulbous or not. It might have a saccate volve that makes it look bulbous while, in reality, there is no bulb.

And I suspect that the ring actually is a part of the volva. I don’t think it belongs up there – too dirty, and isn’t attached to the stem…

Amanita porphyria is unlikely to have a striate margin on the cap.

The highest probability is that the spores of your material will be inamyloid, placing it in Amanita subgenus Amanita. The fact that the mushroom seems to have a bulbous stem base would require placement in Amanita sect. Amanita. Do you agree that the stem base has a distinct bulb?
