I am in the process of trying to obtain a few commonly sequenced genes from some of the Vaginatae that have been sent to me from Europe by you and other kind collectors.

I look forward to another addition to collections to be examined. I hope I have more data to report soon.

Very best,


Material sent to Rod two days ago.

for the beautiful additional micrographs!

I’ll be curious to hear where this amanita ends up.

Some more data added.

I made a preliminaire analysis of the specimen and added some micrographs to this observation.

Dear Amanita lovers;

To Rod: I’m glad to send the specimen, but only in the beginning of the year to come, just to avoid “strange mail disappearance” in Christmas time.

To Debbie: Everything is small in this mushroom, after drying it has a cap with 3cm in diameter and a stem with 4cm (to the extreme of volva). For me it has a clear annulus, but very fragile and start breaking. A piece remained attache to the stem in the dried specimen.

Best regards to both of you;

is that an annulus, Zaca?

or just a bit of UV that has traveled up the stipe?

That is very kind of you.

Yes, I would like to examine it very much.

Very best,


I have the specimen.

Should I send it to you?

Is there really no specimen available?

Is just a tiny specimen.

Hello, Zaca.

It’s nice to seen you posting another Amanita. It looks very interesting.

Since the ring on the stem seems rather robust, my guess would be that the specimen belongs in the Caesareae. It is now well-established that there are ringed species in the Vaginatae; however, most of these have weakly structure partial veils.

Very best,

Rod Tulloss
