There is 0 % possibility this is A. heterochroma , 1 for the habitat: you were under Quercus here and A. heterochroma has been only found near to San Gavino under Eucalyptus(!!!) in just one (burned now,sigh) location; 2 i see some red on the stipe base ; and 3 i thought i have seen a yellow veil so i thought about that species but i was wrong and you right since the main feature is the yellow partial veil and not the universal veil as i remembered ,but A.heterochroma has a grey universal veil on yellow cap as shown on the other sighting here on MO.Next time you are here send me a message.

But the annulus isn’t seen in this photo

David, from what I can find on Amanita rubescens var. annulosulphurea the main feature to ID depends on the presence of a yellow annulus which is not visable in this photo.

R. E. Tulloss who gave the A. heterochroma ID suggestion for this mushroom was involved with Salvatore Curreli in naming the species Amanita heterochroma.

Oh, what a camera problem. EDIT

I once got the chance to get a good macro series of shots of Amanita subcaligata in Colorado. I had nice equipment at that time. The camera dropped down on a copying stand into a white “doll house”-like structure that reflected the light from two synchronizing strobes (to really reduce shadow a great deal). I took all the shots with the manually set timer set at a speed that did not synchronize with the flash (1/60 sec. was required). I got nice picture of segments of stipes. Arrrrggh! I have never seen the species in a fresh state since.

Very best,


Thanks for the corrections Rod!

I had forgotten that our foray group had found an Amanita heterochroma specimen in addition to the specimens that Salvatore Curreli brought with him to show us, but now that I check the species list that Salvatore made of mushrooms found by the foray group at the end of tour, I see A. heterochroma is on it. Too bad I was using a new camera that I hadn’t learned put objects seen in the center of the viewer at the edge of the final photo.

The geography and the cap colors (especially the brown disc)…

suggest that this is A. heterochroma.

There has never been any mention of brown associated with the cap of formosa, which is probably a color variant or a stage of pigmentation development of the true European muscaria.

Very best,

Rod Tulloss
