It helps a bit

At least we can be sure it’s growing on hardwood. With blackish spores it might be a Psathyrella, but in the group of Pholiotas (Hemipholiota) that includes populnea and heteroclita, they are rather dark (“snuff brown”).
Pholiota populnea is sometimes described with an aromatic smell too.

Changed name and other varieties on log

Other varieties on log consisted of:
Tree Ear (Auricularia auricula)
Common Split Gill fungi (Schizophyllum commune)
Thin-maze Flat polypore (Daedaleopsis confragosa)
There were 2 very decrepit unknown crust fungi that were past the point of ID’ing and what looked like the remains of Radiating Phlebia (Plebia radiata) but was discolored and dry.
The odor to these white shaggy mushrooms was VERY distinct…I went to the neighbors to have them sniff and all agreed a definate strong gasoline-like odor. All wrinkled up their noses and such (without me saying first what I thought it was). When viewing the spore-print under pure white light the color looked more blackish brown rather then reddish brown.
Not sure if ANY of this helps?

For unknowns we use “Fungi sp.”

Usually for unknowns we just id the obs as “Fungi”, it would be good to change this one, so we don’t have the species “Unknown mushroom” in the site…

A short description

can be found in “Trial key to the species of PHOLIOTA in the Pacific Northwest”. Try Google if this link doesn’t work:
Pholiota populnea is there, under the synonym Pholiota destruens (grows on Populus).

Puzzling with the smell though. It’s indistinct in populnea, but Pholiota heteroclita (growing on Betula and Alnus) has a strong, aromatic smell. There is also another one, Pholiota comosa (growing on Fagus, sometimes synonymized with populnea), which I can’t find descriptions of. What it smells like, is unknown to me.

Perhaps the other species on the log could give a hint about what kind of tree it was?

I think u’r correct?

Thank you! I believe you’re correct with the ID here…I’m still trying to find some information on it…not finding a while lot of WRITTEN…just some photos…do you have any good links maybe?

Possibly albino form of Pholiota destruens?

Only tough, shaggy brown-spored mushroom typically growing from wood I know of. Usually golden to light brown, though.

lol…well u know…I had to post this fellow to see if any OTHER Missourians had an idea so that no one thinks it was some crazy migrant from Kansas…lol
I’m fairly sure the ‘shag’ was part of the mushroom? But….I’ve been wrong before. Don’t however think it was some sort of parasitic sort…..There were several different kinds of fungi growing on this log…but I knew all the other varieties.

Glad you posted this thing

Glad to see you posting this weird thing Glo, even tho folks around the country might get the wrong idea about the strange creatures that inhabit this fine state of Missouri !!! Could it be that the shagginess covering this rascal is something like the secondary fungus Hypomyces hyalinus ??? The other possibility I can think of is Pholiota destruens. I think they can be very light in color and covered with shaggy material. They have brown spores and a distinctive odor.
