Recognized by sight: an Eastern European grisette. beyond that…nice photo montage!
if you dug it up, you would see an even longer stipe, and some sort of membranous sac around an elongated (not bulbous) base.

in my opinion, no veil remnants. Besides that, A. battarae has a persistent volva with elongate hyphae only.

I don’t know what species it is, but that potential UV material on the cap is curious…

does umbrinolutea have a crumbly veil? or is that some other sort of cap debris? or maybe a whole nuther species…???

and the missing black gill edge are of no taxonomique value? I ahve found them always to be black in Amanita battarae.

By the way, in two weeks I will be for several weeks giving courses in the Thüringer Wald and will be bathing in Amanita battarae, submembranacea, fulva and regalis :-))

With some slight hesitation, I suggest Amanita umbrinolutea

I suggest A. umbrinolutea as a possible determination of the material in the present images. Most illustrations of this species have more red in the brown color and more yellow in the lighter zones; however, I notice that the specimen is drying around the edges and has probably had the cap exposed for a day or more. Hence, now of pigmentation due to UV light may have taken place. The host trees are appropriate to what I know of the species. Perhaps a European MO user will shed some additional light on the issue.

Amanita umbrinolutea is one of the species for which both a brief description and technical information are available on the Amanita Studies site.

Very best,


you are not the first to be bested by a deeply rooting amanita!

and even if you do manage to get it out intact, the cap inevitably will fall off in transit…darned free gills are no help at all in holding it on!

interesting one without name!

I will be much interested in what Rodham comments on this one. Unfortunately we don’t know the volva characters.
The cap zonaton leeds to Amanita battarae, but the colour is too grey and the gill edges are not blackish. And the stipe looks as if the volva doesn’t get rusty coloured, but this is only an assumption.
If you find that one again, try to get it complete, make fotos and dry some specimens. I would expect it to be a undescribed one.

i tryed to dig, and there was a wery long stem under ground , but did not dig deep enough and cracked it before I culd see the bottom. so your definition is probably right.
