This is a lovely set of images of a species that I have only seen…

in Dr. Tsuguo Hongo’s watercolor painting.

At least for a short time, Dr. Z. L. Yang (in his 1997 thesis) thought this species might be the same as Amanita fritillaria originally described from northern India. Dr. Yang pointed out that the stipe of A. spissaceae is more decorated than that of A. fritillaria as he understood the species. Your photo clearly shows the decoration.

GenBank now includes a number of distinct sequences purportedly from A. fritllaria or A. spissaceae. It would be very interesting to know how many distinct sequences (and, thus, possibly, distinct species) have an appearance that suggests assignment to one of the two names.

Since you have found a beautiful specimen in the “group,” I’m curious to know if you have an accessible lab that could obtain sequences from a specimen documented photographically in such a nice fashion.

If you don’t have such a lab nearby in Japan, I offer to do what I can with regard to understanding the material to which you have access. If my colleagues and I can successfully derive one or more gene sequences, I would make them available publicly via GenBank and the WAO website.

Congratulations on your find.

Very best,

Rod
