The part of the ring on the second collection was resting around the upper part of the stem
It fell off when I got it back to the house.
(I guess the other part fell off in the woods).
I’m not sure if it was the same of different in the original observation.

and the partial veil of the specimen in the second set of pictures was not really fragile. I guess technically it could be considered fragile but I thought it held up fairly well when I peeled it back.

I’d agree that the second collection appears to be Amanita ravenelii and I see what you’re talking about with the white filaments at the bases of the warts when I blow up the picture to full size.
and yes, the ID of the original observation will have to remain up in the air. Wish I would have collected it.

I have not looked at the spores yet and do not have any spores from the original observation, only from the specimen in the second set of pictures. My nephews have been running around the house grabbing everything off tables and throwing toys for the past…going on a month now, so I decided it would be best for my microscope to be put up for the time that they are here.
They’re heading back to Iceland this Thursday, so after Thursday my microscope will be free!


yellow gills

I was considering some possibilities for the second specimen (we have more data from the photos). The yellowish gills were striking in the cross-section so I checked my notes for subcokeri, daucipes, ravenelii, and rhopalopus. All can have yellowish or cream-yellow or yellow-cream gills…more or less. My notes would indicate that I saw the strongest yellow ting in A. daucipes. On the other hand, there appwars to be a white fibrillose layer at the base of the volva in the second specimen; this is NOT present in any of the listed taxa except A. ravenelii. Color is a more variable character. The characteristics of the volva were critical to the taxonomy of the lepidellas in Bas’ view. I could be misinterpreting the pictures, however. Do you also see a layer of white filments covering the cap below the somewhat pinkish warts? If so, then I would suggest A. ravenelii for the second specimen. I suppose the ID of the earlier one will remain on open question.

I notice they don’t have recurved scales on the top of the bulb. Is that broken ring of limbus internus something that was around the bottom of the stem when you sectioned the fruiting body? Also, note that the underside of the partial veil is floccose and not connected to the stem by a web of fibers on the underside. Was it different in the original mushroom. I’ll bet (also) that the p.v. fell apart rather easily in the second collection.

I agree with you that the two taxa may be different species.

(I’m back in NJ.)

Did you get a chance to check spores on either of these specimens?

To me, the larger specimen that I collected looks as if it could be a different species…
What do you guys think?

I actually did take pictures….I just forgot that I did…

Until I looked in my iPhoto. I’ll post the pics in just a minute.

The fact that

the warts on the cap are pinkish suggests that this could be A. subcokeri (a provisional name). Amanita cokeri generally doesn’t show this color change; and subcokeri does. I’ll be away from my computer a lot of the time for a period startin 7 July 2011. I hope I get to check in to see what the spore measurement results are.


There were two…

There were two of these growing within about a foot and a half of each other , I collected the larger specimen yesterday but was unable to photograph it.

I’ll put the spores under the scope when I have some time…
