that american observers have so many varieties of muscaria to choose from.
In Scandinavia (yes, I can only speak for that limited area..) we accept a wide colour variation in one and the same species. This one would easily pass as the ordinary muscaria if I found it at home.

Of course you have different forms in the vast North American continent, but how do you tell them apart? I’m not sure that they are different enough to deserve species status. And, to be honest, what purpose does the status of a variety serve, if they are known to be polymorphic and can be expected to have transitional forms?

That one of the world’s most iconic fungi clusters still has so much confusion.

Of course you could say the same thing about Morchella.

Thanks Irene, I have read that paper, its does not address all the niche geographical environments like the subalpine and alpine areas of the eastern United States nor is the sample size large enough to start creating species names.
Preliminary results do show the possibility of at least one subgroup in the east.

That paper also supports my theory that Amanita muscaria does not occur in the south eastern half of the U.S. as traditionally thought.

In the west at least 3 new species will likely be created, I think the same is quite possible in the east also.

I’m actually gonna stop using these provisional names like “A. amerimuscaria nom. prov.” until some of this gets cleared up or published.

Extensive DNA work has been done

Let’s see if the link works here:

on this group also. Didn’t save these but I suspect we’ll see some good DNA data on similar material in a couple of years.

It would be nice to get some DNA from these eastern sub-alpine finds, they don’t look like your typical eastern variety.

guessowii versus persicina clan fight

is confusing me. Herbert, did you figure out how to vote twice? Also don’t understand how 4 votes for var. guessowii vs 3 votes var. persicina comes out var persicina as current winner. I’m still going with var. guessowii and Rod Tulloss is one of the votes for guessowii.
Habitat was red spruce at about 5500ft.
