Hymenopellis furfuracea

Yeah, that’s a pretty close match. In my case the head was actually wider than the stem was tall, but looks like that can very. MycoKey.org doesn’t have it listed. The gills are a perfect match, as is the color of the stem and cap. Yeah I understand about the changing classifications, but what’s the saying … “A rose by any other name…”
Note: The pictures of O. radicata almost universally show the stem longer than the cap is wide, sometimes by a lot. I don’t even have half of the original cap and what I have is bigger than the stem.

This is a large specimen of:

Xerula radicata
Hymenopellis radicata
Oudemansiella radicata

Names are conventions, while a mushroom’s species is a fact of nature independent of what we decide to call it. I have no opinion about which genus name is “correct”, as they change so frequently I can’t keep up.

I do however know that the combinations of characters shown in the photos: long rooting stem, flat brown cap, white rubbery attracted gills, numerous tiny gray dots on the stem… place this clearly in what I first learned as O. radicata, relearned as X. radicata, then X. furfuracea, then H. radicata, and now O. radicata again.

Here’s a link which might help.

Are you sure about that? This looks way too big. The stem is 9" long and the cap is at least 9" in diameter.

I found this in northern Baltimore County in mixed hardwoods.
