good call Rod

of course the ID was made because of the constricted volva…but really any amanita can show a bit of this feature, esp. with age. I have even seen it occur on obvious velosas, from one day to the next!

The volva is not only staining (which it can do with constricta as well) but quite thick.

On the other hand, maybe not a pachycolea…our western grisettes are a taxonomic mess.

gray volva

The volva of A. constricta becomes distinctly gray with time and is more fragile (cracking, breaking, collapsing) than is depicted in your photos, Ryane.

Maybe this is closer to A. pachycolea? It does have a dark ring around the inner ends of the cap’s striations. It is dark. Maybe this is a skinny specimen?

Very best,
