I knew Roger by correspondence and a few face-to-face interactions.

When he retired and was looking for a home for the herbarium that was then at Kingston, he sent me a large and interesting collection of material “on permanent loan.” I will be passing this on to the New York Botanical Garden when I retire. Among the very interesting things in the material is the only known surviving original material of Amanita stranella from Dr. Snell’s herbarium that was, in part, in Kingston. There was also a part of the type of Amanita cylindrispora that Beardslee had sent to Snell, lo, these many years ago.

Very best,


thank you gentlemen!

I’ve been afloat since my old Mycology prof. Roger Goos passed away and I wasted my time doing a PhD in Entomology instead.

This is the most enjoyment I’ve had being a naturalist in years.

I should have said that this specimen reminds me of some of the darker examples…

This would certainly be another candidate for study. Amanita umbrinolutea is apparently a species of Europe and western and Himalayan Asia. I say “apparently” because genetic studies may change our current views on such things. The true A. umbrinolutea as I understand it has alternating zones of reddish brown (umber) and gray-tan. The name means “umber [and] yellow.” The zones alternate, either color can be in the center, and often there are four zones in pictures of the species. For example, you could have an umber zone over the umbo in the center of the cap, then a tan ring, then an umber ring, then a second tan ring. There is something very like this in North America (maybe more than one species, maybe just one). I have seen it in the pine barrens in New Jersey and in the Appalachians (in the Great Smoky Mountains Nat. Pk.).

And, Walt, thanks for the note about the site problem yesterday. I’m not sure what happened, but we had a “failure to display content” problem. Either my son, David, fixed it or it cured itself. In either case, I’m waiting to hear a report on what happened.

Very best,


For the latest on Amanita

Right now the website seems to be having problems but when it is up it is great. It’s creator, Rod Tulloss will likely be shedding some light on the mushroom in your photo. Of course without a specimen, a positive determination may be unlikely.

I notice that Roody does say that “more study” needs to be done to determine if his “American” A. umbrinolutea is the same entity. OH well! Thanks for your help!

Nice picture of a beautiful specimen! As far as I know Amanita umbrinolutea has not been documented from North America.
