You’ll have this one shortly as well.

The rather large free limb that stands away from the stipe…

is sometimes a marker for species destroying angels with ellipsoid spores (at
least in North America. Amanita elliptosperma is one possibility. The group has not been thoroughly studied molecularly so far as I know.

Very best,

As far as I know, all Amanitas from section Vaginatae have striations along the cap margin. Worldwide, I believe there are one or two species of Vaginatae that have a ring on the stipe, and none of these types occur in NA.

I’ve got too many of these saccate ones with the striate margin and this one without the striations. Phalloidae of course!
