Distinctions. Correction.

Correction: The plenitude of volval warts on the cap is not constant in the posted illustration. So I don’t think my previous suggestion is workable. Maybe the marginal striations of the cap are shorter in the species of this observation. My notes show striations in “sp-S01” reach about one third of the cap radius inward from the margin (and give the cap the appearance of species of sect. Vaginatae before the bulb is dug up). The striations in the posted images here look about one-half the length recorded in my sp-S01 notes. I don’t know if that suggestion will hold up either.

More data is needed.

Very best,


Well, this isn’t Amanitasp-S01.”

It’s taken us time to get enough sequences from enough localities to be able to make the statement in the summary.

At present we think that all out collections from Maine to South Carolina are (so far) “sp-S01”; however, there are two specimens representing a different, second taxon (yours from Florida) and another from eastern Texas Pine-Oak woods.

So far I have not tried to build up a list of macroscopic and microscopic differences to help us all know what we have when we collect it; however, your material has warts on the cap, which is often not true of material of “sp-S01” of similar age. If this observation holds up, it might be a first item for the list of distinctions.

Thanks for send this interesting material.

Very best,


Material received.

Thank you for your kind note.

And thank you for sending dried material of this collection. We look forward to receiving it.
