(Oudemansiella radicata)

Description: Sticky, smooth, gray-brown or paler cap with white gills and rigid-brittle, long-rooted stalk; on tree roots.

Cap: 1-4" (2.5-10cm) wide; convex to nearly flat or with broad knob; margin incurved at first; slimy to tacky or moist, smooth or somewhat wrinkled; dark brown to grayish- or smoky brown, sometimes nearly white.

Gills: attached, nearly distant, broad, thick, white.

Stalk: 2-8" (5-20cm) long, 1/8-3/8" (0.3-1cm) thick above ground; rootlike underground base tapering to point; dry, twisted-lined, rigid-brittle; whitish above, brownish below

If you’re saying that X. furfuracea matches this description, I’ll take your word for it.

Does exist but in my experience is rare in North America. In older books most any rooting white spored gilled mushroom was given the name radicata. It was a Collybia and then Oudemansiella and now Xerula. There are several species. The three I see most often are X. furfuracea, X. megalospora, and X. rubrobrunnescens. The latter is uncommon or overlooked as it resembles X. furfuracea. So your ID was not wrong based on using the Audubon guide which was written in 1980 or 81.

key doesn’t even include X. radicata…?

At the time I found this the only guide I had was the National Audubon; their description of Oudemansiella radicata fit this perfectly.
