Observation 136992: Amanita sect. Amanita

Found beneath massive live oak in sand with scattered grasses. Strong evidence for a ringless Florida (or at least southeastern U.S.) panther. I saved and dried specimens ranging in age from about a day and a half up through several days. All of the ones photographed have been dried.

This material has been accessioned into Rod’s herbarium.

that is correct. Sorry for not labeling the collection more appropriately.

I am working with Rod in accessioning collections to his herbarium. Is this observation one of the specimens you sent us In a envelope labeled “Amanita sect. Amanita (possibly subsect. Pantherinae)”?

good eye!

I had missed the bit of material on the cap margin. Hopefully I can get this material to Dr. Tulloss so we can figure it out.

as indiacted by the complete absence of any potentially annular material, then I believe this rules out sp-S01. My understanding of sp-S01 is that it often forms a fleeting ring. But the PV can also cling to the cap margin, and easily fall away. In the second pic, the smaller one looks like it shows this type of marginal deposit of PV material.

does also make good sense. I thought given the complete lack of any ring at even the young stages of some specimens, the bright white nature of the veil remnants (when present) on the caps, and the sort of ocreate stem base that Pantherinae would be likely.

Pantherinae seems like a good possibility to me.

Except I think this also qualifies as “sp-S01”, which is placed into Gemmatae. So my take on this obs is that the more general category of “sect. Amanita” is a good starting point.

I don’t think this obs represents the same species as
The lack of marginal striations and lack of basal volval structure on 136846 appear to be two main differences.

Do you think my collection is the same as yours?
Can you take a look?
