Notes: Exact spot as this find, four days later; a new group has emerged. http://mushroomobserver.org/182018?q=2GcJq
The pinkish tones are more noticeable today in these specimens. Perhaps it is the ‘Pink Panther’.

You have put together a new research program for me. I don’t have answers to these questions at this moment. I’m not even sure that anyone has created a suitably detailed phylogeny with a suitable sampling protocol to tackle your larger questions.
Most of the effort in taxonomy related to Amanita toxins up to this time has been with regard to the amanitins. That work is continuing in labs around the world.
Large, methodologically careful, well-designed projects on toxins went out of favor for awhile; now they seem to be coming back. Certainly there is a lot of recent publication happening (for example) in China.
With relation to non-amanitin, non-phalloidin interest, I know of one worker who got quite exasperated with the publications on the non-protein amino acids that have been coming out now and then. He and his boss are reworking that question with a sampling scheme that I set up for them at their request.
I am beginning to work on getting species of section Amanita sequenced (just two genes when they can be derived…the usual suspects); but I have no big program with regard to section Amanita. I did design a sampling strategy for that section for the aDiv project (Agaricales Diversification or 3000 Agarics). I took the opportunity to sample taxa that do not have sequences in GenBank. That’s what I’m doing in that area right now.
If a lab with the right toxin assay and sequencing tools wants to work in the areas you are suggesting, I would be happy to talk about the sampling design and provide samples where I can.
Edit* You have Amanita breckonii in series Heterochromae within subsection Amanita due to the nonpseudoparenchymatous subhymenium. Is Amanita “sp-N60” close enough to A. breckonii to fall within the same series? Are there any other series outside of series Amanita, besides series Heterochromae, that we could also consider muscaroid (containing ibotenic acid and muscimol)? How does the phylogeny look regarding this chemotaxonomic group? Will you be publishing any phylogenetic trees of this group in the near future? Thank you.
has a very powdery volva.
