The amazing thing is that these guys…

are edible species of section Phalloideae. There are very few (so far as is known) descendants of the pre-amatoxin amanitas that were ancestors of the Phalloideae. Two of them are discussed in our earlier posts on this page.


I’ll agree with A. pseudoporphyria

Since they both look quite similar and we don’t have a specimen to examine microscopically, I will have to agree with you. Thanks again for your help and comments.

On the old Amanita Studies site, Yang wrote:

“It pseudoporphyria is very common and widely distributed in China and often sold, together with A. manginiana sensu W. F. Chiu, in free markets. Amanita pseudoporphyria is very similar to A. manginiana sensu W. F. Chiu, but differs from the latter mainly by its broad ellipsoid to ellipsoid spores and more abundant inflated cells in the volva.”

We don’t have spores to look at in this case; so we can never be sure which of the two taxa we have…or if we have a third thing.

The pictures are good, Ryan. You posted some interesting things from Yunnan.

I’m glad you’re safely home.

Very best,


maybe next summer

Thanks again Rod. I’m currently back home in the States, but planning to return to Yunnan next summer. I’ll have a closer look at the Amanitas there at that time.

For this species…

in Yang’s book (if you can get a copy), check Amanita manginiana sensu W. F. Chiu (an edible, market mushroom) and A. pseudoporphyria Hongo (also, an edible, market mushroom).

Very best,


This may be the species that passes

This may be the species that passes for A. manginiana in China. There is a single color image of the original A. manginiana from SE Asia. All parts are chestnut brown—cap, stipe, everything. Since you are in Yunnan, can you get to the herbarium at the Botanical Institute in Kunming? Dr. Yang and his students are located there. Maybe you can get your hands on a copy of Yangs 1997 thesis on the amanitas of SW China. Many of the species you are seeing may be in that book (it’s written in German, and it’s well illustrated with good drawings). Yang has published many articles on Amanita of China since 1997. Maybe he could provide you with copies or PDFs. Yang contributed text (in English) and photographs for the old Amanita Studies site, which is still on the web and will be for a while. You should check it because it is possible that other Chinese references have names misapplied. Yang did a lot of work on straightening things out!

Very best,
