Looks like lots of what…

I have routinely called “flavoconia.”

Very little to go on in ret’s link. But one difference appears to be a significantly larger spore quotient for sp-36… q values nearby 1.7 as oppsed to 1.3 for flavoconia. Is the striate cap margin a factor here?

Did a little searching here on MO, and there are a few other eastern NA posts made under the heading “Amanita flavoconia” which show at least one reddish-capped mushroom with (faintly) striate/sulcate cap margin.

David, thanks for calling my attention to this posting.

I haven’t been on mushroomobserver lately. So it was nice to have this posting flagged by David.

I’d like to suggest that this might not be A. flavoconia, but the code-numbered species A. sp-36 instead.

No brief description is posted by the macroscopic details are on the technical tab here:


Very best,

cap margin is interesting. But otherwise this really looks like one of our typical local flavoconia types.

From the Amanita studies website description of A. flavoconia… “The edge of the cap is infrequently striate.” One wierd trait can really lead astray!
