Spore measurements suggest that the material we examined was past its prime in terms of spore production. The spores are a littlle short on average and, hence, the length:width ratio is a little low on average. I am still inclined to think the material is wellsii.

Very best,


We will put it to the test.

I hope it is in OK shape for you to work with.

It was a mistake to add that other image which was of a fungus about 15 feet from the others. Rod, I did not collect that one with the concentric spots and the one I cut in half is in the dryer. Sorry and thanks all.

Igor makes a good point.

First of all, thanks for drying the materiall.

Secondly, I hope you’re drying the material shown in the pictures other than the first one. The first one might be wellsii, but…

I can’t tell if the first image shows wellsii; however the remaining images do fit the macroscopic “gestalt” of wellsii.

Very best,

Hi Rod—I popped the mushroom in my dryer when I saw you wanted some. It is not too fresh, but I think you’ll get something usable. As always, I sure appreciate your interest!

… shows UV as warts arranged in concentric circles rather than in a haphazard fashion that is typical of A. wellsii as per the description at http://www.amanitaceae.org/?Amanita wellsii. The remaining pix show fbs that are in good agreement with the morphological concept of A. wellsii.

This is a very interesting find.

Bonnie, I hope you can find more of this species.

I would be very interested in seeing material from your neck of the woods.

Mostly, A. wellsii is known from eastern Canada and northern tier states and the Appalachian Mtns. (south to Tennessee) in the eastern U.S. A collection that was very similar in macroscopic terms was posted on MO some years back from Missouri (if I remember correctly). It was quite distinct genetically from the northeastern material that I had in the herbarium. Now I want to know what sort of variation(s) are going on “out there.”

Hence, my interest in material from your collecting area(s) and other sites away from eastern Canada and New England.

Very best,

Wow, thanks for the ID which made all the sense looking at my prior photo of what I had believed was the “reddest” Amanita muscaria I’d come across in the UP. Handling the stipe of my first example was very similar to the A muscaria but the lack of a volva (maybe my poor digging?) confounded me. Sure appreciate it.
