to the collection site this most recent weekend and found a few more of these. This time I checked for the KOH reaction on the cap and got the yellow color change associated with the Destroying Angel. It was the shaggy covering on the stalk that had thrown me off. I’m more used to seeing these types with a smooth stalk. I also found one with the smooth stalk quite nearby the original collection (23124). It also exhibited the KOH reaction.

Amanita bisporigera?

Since the spores appear nearly globose, I think that supports this guess.

Very best,
