You have sent me material from this observation and four others: 193978 (possibly, A. pseudocrocea), 204746, 204747, and 204749. The latter four are in the queue for the section Vaginatae project. They will go out in the next shipment of samples.
The material of the present observation will be sampled as part of the Phalloideae project. At present we are building a queue while waiting to see if a grant comes in for a collaborating lab.
This material has been received and accessioned into Rod’s herbarium. We have scheduled if for DNA sequencing.

I was unable to secure any KOH, though I will see about getting some soon. In the meantime, however, I will happily dry you a few specimens. I returned to the same spot today and was able to collect several specimens. I will send them to you as soon as I can. Would you please e-mail me a mailing address and any specific instructions for packaging and the like?
Sometimes I change names and sometimes I make a comment and let other people think about it to see if they have a counter argument.
Do you have potassium hydroxide solution? KOH will turn the cap of most collections of bisporigera yellow. In my experience, specimens I’ve identified as elliptosperma do not produce the same (yellow response). I use about 5-10 percent solution of KOH. A more dilute solution will just have a slightly slower response. You could try any strong basic (alkaline) solution. Drano might work. I’ve never tried it. Doing a little experiment is worth more than a photograph alone. You’d have a better case for a name change.
By not changing the name myself, I got a question from you that made me think about an experiment that you could do. I like that series of events.
First of all, thank you for your comment.
Secondly, should I change the name from A. bisporigera to A. magnivelaris?
Because the membranous limb of the volva is standing up straight (with sides parallel to the surface of the lower stipe) and because the base of the bulb appears somewhat pointed. I think that you may have one of the toxic species of section Phalloideae that has ellipsoid spores and four-spored basidia. One name from this group of taxa (in the eastern U.S.) is Amanita magnivelaris.
Is it possible that you could dry this material for study? If so, I’d very much like to see part or all of the dried specimen.
