I have heard some vague comments, but nothing definitive.

Very best,


Other “new” Amanita species…

…I hear that the West Coast’s Amanita franchettii will soon be getting a new North American name.

Yup, David. You’re correct.

The code number has existed since 1980! There are lots of numbers that have never made it out of my notebooks. Hopefully, we will eventually have time to change that. As I said somewhere else, Walt Sturgeon deserves a medal for patience.


ah, the classic good news/bad news joke…

way cool that Walt found a new species in section phalloides. bad news, well, you know…another deadly amanita in section phalloides.

was this one already given a number by you, Rod? Seems as tho you’d be a looooong way from #1!

Walt’s mushroom is apparently a new species

Unpublished molecular data kindly made available to me in digest form by Dr. Zhu L. Yang suggests that the species that Walt has been showing people for over 20 years is indeed a species distinct from those whose names we usually would apply to a species in the eastern U.S. with subglobose to broadly ellipsoid spores and a positive (yellow) reaction to KOH solution. It seems that there is a good chance that Walt is showing us an undescribed species.

We are awaiting DNA results via Rod’s contact for DNA work. I have sent a couple collections to Rod in the past. If I have time today I’ll make another collection which I will send to you or Ann.

A ocreata but…

…without all the dust. Why are they always so dirty? Our eastern Destroying Angels are always much cleaner and prettier.

a brand new collection?

IF recent, is there a fruit body? Sure would seem to be a good DNA candidate, and I’ll bet that Anne Pringle would run it in a second.

PLEASE, go back and dry some! We need conjecture no longer over what this is; the tools for a determination are out there.

From my perspective at home, it resembles our western ocreata. Did it show more green in the cap at your end?

Cool find!

Identified a collection of this as Amanita phalloides. One major difference between this species and A.bisporigera & A. phalloides is that the volva while saccate becomes quite thick only a short way down from the top limb.

Invoking Kauffman’s spirit

I’ve long wondered what mushroom CH Kauffman was seeing way back when in the Great Lakes region that was an “umber brown to smoky olive” Amanita with a saccate volva and that was so common “throughout the State” (presumably Michigan). He called it Amanita phalloides and his description seems to match. Maybe this mushroom here is what he was seeing. Is phalloides NOW in Ohio? And was it back in the day of Kauffman? And if not, what was he seeing in the Great Lakes region?

I have four locations

for this species in Northeast Co. Ohio (not China!)All locations are lawn areas under red oak. There were over fifty fruiting bodies under one tree yesterday.

Maps show central China for US matereial

if the longitude is E instead of W or (when E and W are not used) is given without a “-” sign in front of the degrees.

Is this a new collection of your heavy-duty, cemetery-haunting friend, Walt?

Wow, Walt, which one is THAT? If you were on the West Coast you’d assume it was phalloides. And why does the map show central China?
