Alright thank you, I appreciate it a lot!!

My first guess would be wellsii.

But you had it in your hands. The yellow stem is very unusual for any of the muscaria-like taxa. In your area, if this was in the muscaria group, it would be what is currently called Amanita muscaria var. guessowii.

I think you could take a look at the two descriptions wellsii and var. guessowii and make your choice.

Here’s the page for var. guessowii:


Very best,

I see what you are saying about the ribbing on the cap. Possible change- Amanita muscaria?

It could also be one of the North American dominant muscarioids without its veil…maybe.

This probably isn’t A. parcivolvata because it lacks the long grooves on the cap edge.

Were you collecting in an area with poplars or birches and blueberries? This very large for __parcivolvata_, also. Too bad you don’t have it on hand any more. If it didn’t ever have a partial veil, I think a good bet would be A. wellsii. It’s been mistaken for parcivolvata by collectors in northern states of the U.S. in the past.



Very best,
