Notes: I’ve hunted in hundreds of acres in 3 different locations here in SWFL and there are thousands of these poppin up everywhere.
99% of finds are in extremely sandy soil where boletes, Laccaria, and Lactarius mushrooms are usually found.
Pine/sabal palm areas. Also around oak hammocks.
SWFL’s environment can go from a swamp ecosystem to a desert ecosystem in 12 inches… keep that in mind when viewing my observations.
ALL finds over the last week has been this same mushroom.
Also, I originally thought these were Amanita phalloides, but another local hunter told me they are A. bisporigera from his experience

so, basically, unless you have a tricorder in hand (or are friends with Karen Hughs or other DNA lab access folks), these are basically indistinguishable in hand from bisporigera? Did any of these recent collectors notice a “garlic odor?” That is certainly distinctive.
I thought that even bisporigera sometimes had four spores on its basidia.
ARe the spore shapes between the two species strikingly different, or does it only show up after many dozens of measurements?
This material is A. suballiaceae. Since that species was described from Alachua County, Florida, it’s nice to have a new Florida collection. The range of the species is very broad (as we are learning from the generosity of many collectors).
The range is described on the technical tab here:
http://www.amanitaceae.org?Amanita+suballiacea
The species can be separated morphologically from A. bisporigera by the shape of the spore and the 4-spored basidia. Both species turn yellow when KOH is applied to the cap.
Very best,

This material has been received.
Very best,
Rod
the description… sorry y’all.
added some pictures too.
cheers
Actually, on the large cap surface lower middle of the photo, the sand is obvious. Cap surface in upper potion of photo is blurry.
Looks like the small cap may have a partial veil clinging to the gill surface. But the focus isn’t sharp enough on this part of he pic.
ID, not so much.
was there a partial veil or skirt?
whether the cap surface is warty or merely covered in sand.

Yes, the spore shape is very distinctive…broadly ellipsoid in suballiacea. When I have the time to measure spores of suballiacea, I can segregate it cleanly from other white members of the Phalloideae in eastern N. America. We have some spore data on for this species on WAO. I’ve never detected an odor; but I probably didn’t think of sniffing when I collected something I thought was bisporigera. I’m not sure of this, but I think that suballiacea can be very robust, which might separate it from bisporigera, but not from sp-O01.
One of the reasons for reporting 4-spored basidia sometimes exclusive on bisporigera is that we didn’t know how many globose- to subglobose-spored species were present within the general notion of “eastern North American white species of Phalloideae that turn yellow with KOH on the cap.” Walt Sturgeon collected Amanita sp-O01 over and over again and said it was distinct from bisporigera, and he was right. There are at least two or three more. Q. Cai et al. got distinctive genes from a lot of the material that I sent to Kunming. When I looked this morning, they hadn’t posted a table of all the GenBank accession numbers with their new paper.
I’m going to get the sequences organized and onto WAO with links to GenBank as usual. This will take a little time, but I’ve been working on it this a.m. (resulting in the MO postings on observations that were sources of DNA sequence by Q. Cai and L. P. Tang and others among Dr. Yang’s students.
Very best,
Rod
