a possible explanation for that odd volva…

this mushroom was collected on the 15th but not illustrated until the 17th. I have observed collapsing or post-pick flaring volvas on other amanitas that I have collected and stored. I always illustrate what I see, so my drawing here does NOT show how the mushroom looked in the field, just what it looked like after a bit of aging. the pink color was apparent and striking in the field, however.

the various folks (including Bill Roody, who has seen pink bisporigeras) who looked at this amanita at the NAMA foray at Pipestem (where I also illustrated it) thought it to be a bisporigera. But I don’t know if anyone scoped it or even dried it, for that matter. Probably not, since it wasn’t collected as part of the “official” NAMA foray.

The flaring volval limb and the shoulder on a not exactly subglobose bulb raise questions that cannot be answered. If the spores could be investigated, they might show that the species was A. elliptosperma.
