I guess we can’t really prove an affinity to A. pantherina. I’m inclined to think that cap colors are not very supportive of A. pantherina — although, on the other hand, I know there are sometimes pallid specimens that people place in A. pantherina. At any rate, I don’t think that there is any evidence that I know of that the European A. pantherina exists in the U.S.

Since we don’t have the stem base, we perhaps should retreat to Amanita sp. for this specimen because we don’t know whether its spores were inamyloid or amyloid, and we don’t know of any indicator that would push us one way or the other. Unless… Did you happen to notice whether the short gills were squarely trunacted on the end towards the stem?

What about A. franchetii sensu Thiers?

Stem was white, about 15 cm long, with skirt-like annulus. I messed up the volva in digging it out, so not sure if volva had collar-like edges or not.

What about…

the bulb and form of the volva on the bulb? Do you get an image of the stem?
