unusual for regalis

I would agree with Irene that this collections looks somewhat like “our” regalis, but differs in some respect. I was thinking about what makes the difference, which it is obviouse to me, but difficult to put into words. I think it is the general brownish colouration of the stipe and the warts, which I have never observed in regalis from Germany or Scandinavia. Ours always have white stipes and yellow (rarely whitish) veil remnants, but never become felsh-coloured or brownish anywhere. I’m not convinced that this exemplaire would be molecular the same as our regalis – and if they would, I would think about the truth of molecular results in closely related species ;-)

This is a very beautiful specimen Monkeycyst!!!

Thanks, Irene.

It would be nice to get an input from eastern Asia on this post. If A. regalis is not supportable, then I’d have to back off quite a bit because the rings of warts are present on at least one species of the Validae that is known from Japan—A. sepiacea. From my understanding it is quite differently colored and has distinctly pyramidal warts in rings and around the upper “half” of a broadly fusiform or clavate bulb. There are good illustrations in Dr. Z. L. Yang’s 1997 thesis (in German) and his recently publication of a floristic work in Chinese on the Amanitaceae of China.

regalis..

maybe something close.. It looks larger and more robust than our regalis though, and I don’t recognize that thick ring either..
Amanita regalis in Europe is a typical species in rather rich spruce woods, and earlier in the season than any of the other Amanitas.

I don’t think this is A. rubescens.

This is not Amanita rubescens, nor it it the Asian rubescent species, A. orsonii. Neither of them has the beautiful rings of warts over much of the bulb that are seen in the good pictures of Monkeycyst.

I believe that the warts may have originally been yellow. This may be a specimen of Amanita regalis. Would Irene like to comment on that?
