Is there a format for naming an unknown member within a group?

I’ve seen “Amanita vaginata group,” “Amanita sp. (Section vaginatae),” and “Amanita sp. (Vaginata group)” just in reference to unknown grisettes, not to mention others.

so many grisettes, so few good names…

I don’t believe that this mushroom is a pachycolea either. Not that I can give you a better, alternative name, even if you had shown more detailed photos.

Pachycolea is a BIG mushroom, often profoundly umbonate (a big knob in the center) and usually two toned on the cap (rarely three). Its universal veil is absurdly thick and stains reddish orange. It is one of the very few grisettes for which we seem to have a good name.

Anybody need a PhD project? ;)

“veil and volva”?

I don’t see any annulus on the stipe. Amanita pachycolea wouldn’t have one. Unfortunately, we can’t see the volval sac in the top two pictures. The third picture may be a separate species. None of them look very much like pachycolea from my limited experience. I’m curious to see what other folks have to say.
