in the spirit in which it was sent.

none of the amanitas that came in that day were in good shape…from the get-go. Still, in this drought year, we were grateful to see ’em.

It’s not just the volva

but the long-striations that are more suggestive of A. pachycolea to me.
And if you are begrudging your handling, I would congratulate you! It doesn’t look badly handled at all.

sure, you might occasionally see a gray inner volva in a pachycholea, esp…

if it is fading. but you almost if not always see a gray inner volva in a constricta, like these classic examples here:

http://mushroomobserver.org/image/show_image/1004

I IDed this mushroom in hand, not by a photo after a lot of handling. In hand, it was more like a constricta than a pachy, but obviously the two species share a lot of characters, and those characters can be variable.

BTW, Darvin was there the next day and also saw it. Not a lot of amanitas this fall/winter, so it stood out.

That’s two yes votes from folks who were actually there.

But I guess we can argue ambiguous mushroom IDs til the cows come home. Have fun with that!

Long striations and inner volva

A. pachycolea can also show a gray inner volva (not sure of the frequency).
Here’s an example:

The volva doesn’t look all that constricted to me here

just saw this…

I haven’t been wasting I mean spending as much time on MO lately. ;)

This amanita was IDed at the Fair as constricta. Both constricta and pachycolea can have staining on the volva. Both species can also get constricted volvas at age. The grey volva interior throws it into the constricta camp, slightly visible in these photos.

Looks like…

perhaps the striations are too long for constricta and the cap coloration wrong for pachycolea.
