No specimen available

one of our most beautiful mushrooms. It looks kind of like a Pholiota, but the spores are white, unornamentedm and amyloid (see third picture). The scales are an integral part of the cap and stipe. No genus existed for it, so we elevated Armillaria subgenus Leucopholiota to genus level. For the interesting story of how I got to name this mushroom, along with Orson Miller and Alan Bessette, see http://botit.botany.wisc.edu/toms_fungi/sep2001.html

The genus was published in

Miller Jr., O.K., Volk, T.J. & Bessette, A.E. (1996). A new genus, Leucopholiota, in the Tricholomataceae (Agaricales) to accommodate an unusual taxon. Mycologia 88(1), 137-139.

I Don’t know where this belongs. We should probably sequence it, except I don’t ahve the specimen any more. I am guessing it will end up nearer to Cystoderma or Tricholomopsis than to anything else. But I don’t really know.

I did not see the specimen at the NAMA foray in WV, but i just saw the writeup about it in the NAMA newsletter. No one showed me the specimen there. I am sad.


This was found in september 2004 or 2005. It is keen.

This one stumped the stars at the West VA NAMA foray last summer.

Surely you didn’t just collect this mushroom in Michigan! Has the world gone mad? Shouldn’t you be using the city plows to look for snowmelt mushrooms??!
I am assuming that it is todays post and perhaps last summers collection…

“The idea of it being an albino spored Pholiota has an appeal to it.”

Hmm. The genus name as well as macroscopic features suggest it is most relative to Pholiota, though, the history of it having been split off from Armillaria suggests it might be more related to Armillaria than Pholiota.
That was my assumption anyway.
But you bring up a very good question.
Tom, what genus is Leucopholiota most closely related to?

Thanks for adding this uncommon and unusual species. Has it been sequenced yet? I wonder where it will land. The idea of it being an albino spored Pholiota has an appeal to it.
