We received DNA sequences from this material over the weekend.

Sequences were derived for both the “proposed fungal barcode” gene and the nrLSU gene. In both cases, the sequences were somewhat similar to an eastern North American taxon with the provisional name Amanitasubnigra.” This was an interesting find; thank you for sending it to me.

I hope you have the good fortune to find this species again. If you do, I would like to ask you for information about its dimensions.

Very best,


You’re welcome, Rod

I think we’ll try one more time next week.

Thanks to all of the folks who went on the search. I really appreciate the effort.

Dick Bishop, Pam Buesing, SK, Don Moore, and Sallie Tucker Jones of the OMS Mycoflora group tried today to find these mushrooms. They weren’t there.

After examining both an immature and a mature basidiome from this collection,…

I feel that the specimens may have been influenced by some environmental factor. The water soaked appearance of the stems suggests that there may have been some agent decaying or otherwise damaging the stems. At any rate, the shapes of the spores are highly irregular indicating some abnormality. The spores from both immature and mature material are dominantly subglobose to broadly ellipsoid at maturity; however, in both cases the larges spores and immature spores still attached to basidia can be very highly variable in shape. Probable giant spores were seen in both cases (this is usually only the case with immature gills). Spores were seen shaped like “S” or “C” or like peanuts, gourds, sausages, clubs or more irregular shapes.

This reminds me of the holotype of Amanita lactea in which the same craziness of spore shapes was seen…there was even a spore shaped like a flat worm with a triangular head and two “eye-spots” on its face! (That’s one for the Journal of Irreproducible Results for sure.) All other material of lactea proved to have smaller spores of more regular form. Clearly something was wrong with the type collection (which consists of many specimens…all screwy).

My conclusion is that it would wonderful to recollect sp-WA03. We can try to extract DNA from the present collection to help us recognize a second collection in that manner…because, I hope, a second collection will have normal spores.

This is a very interesting species; and I hope to see it again.

A very curious collection.

Thanks very much for sending it to us.

Very best,


A techtab for this taxaon is partially developed.

The spores and their development…at least in immature fruiting bodies is rather unusual…at least in the first of your specimens that I examined. See the webpage for further developments.

Very best,


Thank you for sending the material, Sava.

We are just beginning to organize information about several new collections of sect. Vaginatae that we have recently received. It is not a fast process and it takes many hands to do the job, but I am glad that we can work toward a body of knowledge that is broader and more precise than the body of knowledge that we received from those that went before. That is one of the fragile pleasures of civilized life.

Very best,

Thanks again for your interest. I’ll send you both of my Aug 11 Amanita collections when I come back from vacation (Sept 2).

I see that you retained dried material from this observation.

I would very much like to see it if that is possible. I am also interested in the other observation you posted this morning.

Very best,
