RE the COMA foray…

The number of undescribed species of sect. Vaginatae was pretty large.

The Validae were well-represented with at least one surprise: We’ve been finding something entirely white with the pleasant odor A. submaculata in recent weeks in NJ. We we got a nearly identical mushroom (no microscoopy done yet) that was entirely odorless (two collections) in CT.

There were six species in sect. Lepidella (large for a foray in northern pine-hemlock-hardwood forest in Connecticut…in my experience).

There was a probably new species in sect. Amanita that was very reminiscent of the European species A. eliae.

We did not find A. sp-N50 (a species somewhat similar to A. siamensis), but we did find one of the brown msuhrooms that we called “penetratrices” (plural of “penetratrix”) during the 2009 foray when we lost a chunk of material due to loss of power to dryers one night. For a little tiny bit of the tale of the “ones that got away” that year, see

http://www.amanitaceae.org/?Amanita penetratrix

It seems we can actually put some data on that page now.

We managed to photograph everything that was new (some in situ as well as in the lab), but there were at least six that had to go into the dryer without written annotation having been created.

Bill talked to me at the end of the foray about getting some collections of the unusual Vaginatae onto MO if he runs into them in a more leisurely atmosphere than the madness of a 40-to-50-Amanita-species race-to-ID-before-they-rot.

At one point Mary, Cristina, and I were all working on photography; and someone asked, “Does it really take three people to do Amanita?” Well, last weekend, we might have been able to do a complete job if we had had six people. The first day wasn’t like that, but by Sunday night it was just plain crazy. A trance-robotic state was the ideal. Describe ’til you drop. Then grit your teeth and put everything else in the dryer…that was the required attitude.

Again, :-?


For the cap and stipe color patterns on this one…

take a look at these taxa on www.amanitaceae.org:

Amanita sp-F11 (first known from Florida)

Amanita sp-S10 (first known from South Carolina)

It would be very cool to get some macro data and dried material from Devil’s Hopyard if you see this critter again!

Very best,


sorry that I missed THAT foray…

sounds like a plethora of cool amanitas.

The current classification seems appropriate.

After this past weekend, I’m beginning to think there is something very strange going on in Devil’s Hopyard. As you know first hand, it appears that we had between 40 and 50 distinct species of Amanita at the COMA Rogerson foray…and a devilishly large number came from Devil’s Hopyard.

As if there weren’t already enough work for this winter and twenty more…



thanks Rod for your response

I wasn’t too sure that this was Mary Banning’s mushroom but I’m glad you called my attention to the details of the cap color. I do find this mushroom most seasons and the next time I do I’ll dry it and send it. So maybe a better designation here would be Amanita sp. section Caesarceae?

Amanita banningiana?

Amanita banningiana doesn’t have a red umbo at any stage of development in my experience. However, there are a couple of other possibilities for your material…all having only codes instead of valid or provisional names. I see that you didn’t retain a herbarium specimen.

If you see this fellow again, Bill, and you have the opportunity to dry it, I’d love to see the material.

Comparable coloring among taxa in sect. Caesareae can be seen in Amanita sp-F11 and Amanita sp-S10 on WAO.

Also, I’d like to call your attention to Amanita sp-N12 (seen once in 33 years of collecting in the NE U.S.); it is probably not the same species as the material of this observation; however, I’d sure like to see more of it.

Very best,
