Summary: A. bisporigera

Looks like it to me, and there’s a suspicion among scientists that all of the tall white destroying angels are genetically the same species.

(If they’re going to roll up all the destroying angels that aren’t white A. phalloides into one species on the basis of DNA, though, I really wish they’d use A. virosa. That name actually means that it’s poisonous, and is a well known one unlike A. ocreata and some other names used for what may be really the same species. Meanwhile A. bisporigera and A. verna for the merged species would be misnomers, since it’s not always two-spored nor is its fruiting confined to the spring months!)

Summary: Amanita bisporigera?

Next time you see this one, try 5% (or slightly stronger) KOH solution on the cap. If it’s A. bisporigera, you should get a strongly yellow reaction. While there are other white “Destroying Angels” in the eastern US, not too many occur in upstate New York. Another one is A. magnivelaris, but this has a large, FELTED annulus and ellipsoid spores. There is a key to North American species of sect. Phalloideae on the Amanita Studies website.

Very best,

Rod Tulloss
