Amanita count at COMA

Yes, Rod, the count is rather low if my memory serves right. There might have been a few more obscure species (mostly in sect. Vaginatae) in addition to the ones I mentioned, but I think that was it. I went through the 100+ regional species list on your satellite website to refresh my memory and could not come up with additional names. I’ll ask for the COMA species list, when it’s ready, to be sure.
I don’t know what you mean by “the old sites”. This foray was COMAs’ second year at the Berkshire Hills in Copake. There was a total of 9 sites, all of which fit into a circle with r = 10 mi centered at the point where the borders of NY, MA, and CT converge (the “3 corners”). Six of them were clustered next to each other in the SW corner of MA and the other 3 were to the north, south and west of Copake in NY, respectively.
I visited two sites (Taconic SP and Mt. Everett HS, both in MA) and they had similar habitats: dark and somber coniferous woods, with hemlock as the dominant species, intermixed with a bit of oak, birch, ash and other less common hardwoods. The only amanitas I recall seeing there were amerirubescens and bisporigera. I also found what appeared to be dainty A. banningiana (it was definitely in sect. Caesaria with a small white ring on a white stipe, a friable saccate volva and an orangish-brown striated cap reminiscent of fulva), but messed up collecting it and then it incurred further damage when mushrooms shifted in my bag.
I think most of the sites had this kind of habitat that appears to support a only a limited variety of amanitas — well, at least in early September. And, yes, it was dry, but not as dry as in NJ. According to the COMA recorders, they counted 327 identified/verified species on Monday morning, which is an average number for their foray. IMO, collecting was very good despite the dry conditions (the last rain Copake received was on Aug 25), and there were many fresh and young mushrooms in great shape. The woods’ soil retained moisture well and probably had the benefit of a copious morning dew as the nights there averaged in the low 50’s. John Wheeler and I went onto a blitz foray at Mt. Everett HS and filled his basket with over 100 species!

That is a rather low amanita count for COMA. Did they go to any of the old sites?

Was there a lack of rain?

Very best,


You are welcome, Rod…

This one and the other three were perhaps the most interesting species we found at COMA.
There is one more collection I preserved for you — it’s a muscaroid type, but we weren’t sure it was the generic amerimuscaria. Leon Shernoff took the pictures, so I will ask him to post them on MO or to forward them to me.
Other than that, the other amanitas we collected at COMA were IDed with little trouble. I recall seeing abrupta, amerirubescens, bisporigera (and lots of it), brunescens, citrina, crenulata, flavoconia, multisquamosa, persicina (possibly misidentified) and one example of onusta on the ID table. That’s about it…

Again, Igor, thank you.

This seems to me to be in the group that includes A. fulva.

At one time, I would have used the name without hesitation. Now we have genetic evidence for at least three fulvoid species in northeastern North America. This could be one of them.

Very best,
