Oakman Ringless Amanita (Amanita oakmanensis)
Growing on a ridge side below hickories and oaks (in moss) in a dense mixed hardwood/coniferous forest. Gordon County, GA, US. August 18, 2018.
Zonate cap. Stem hollow. I, unfortunately, made a mess of the bulb when trying to dig it out from deep moss!
Seems like it may be the unknown Amanita I sent off for study in June! https://mushroomobserver.org/320883?q=YFL2
UPDATE!!!
I'm in a bit of shock right now, but I am having my first mushroom described. There have been happy tears this morning.
Rod Tulloss updated me with the sequencing results this morning (which are, as usual, way above my head):
" A good nrLSU sequence has been derived from the voucher of this observation.

The sequence has a small ambiguous region early in the nrLSU sequence and ambiguities are so numerous in the nrITS that I made the decision to only use the “half” of that sequence that connected with the LSU sequence. This is the first case of sequencing this particular species. However, I suspect that all attempts to sequence this mushroom will prove to have difficulties with editing that we experienced in this case.
The species has the initial character segment of nrLSU that determines the “series Penetratrices”. After looking at the images further, I will have another sentences or two. Thank you very much for sending me something puzzling."
" I think that I can’t resist “oakman” in a name. It is totemic.

I propose the name Amanita oakmanensis nom. prov.
In a BLAST run against GenBank’s current data set, the closest species is Amanita trygonion with a genetic distance of 1.0% (10 differences out of 974 characters).

I swamped right now, but we will aim to create a more than skeletal page at this address:

After carefully revisiting the cap coloring I think there are two colors. The shadows in the striations give the illusion of a dark zone to the striate region of the cap. I find this is a rather common phemonenon."
