I’m guessing that this was a fairly small species.

Your first photo is very good for diagnostic purposes.

The cap has powdery volva on it and an appendiculate margin, and there is a membranous outer layer of the volva which is partially on the cap and partially projects up as a limb from near the outer edge of the bulb. The bulb is distinctly radicating and pointed.

These characters fit very well some of the oddly limbate amanitas Bas placed in his subsection Limbatulae. These often have very narrow spores as well as other oddities.

Almost all these species are in sandy soils of semi-arid regions or coastal plains (in which rain rains into the soil very rapidly and forest fire is subsequently a danger). Almost all of the species are in the Se U.S. or in SW Australia. One is known from SW Europe.

Interesting material. Congratulations.

Very best,

Rod
