Summary:
A notable feature is growth on hardwood logs and stumps. Other features include a convex to flat, hoary white cap, adnate to short-decurrent, whitish gills, a whitish stem that is often curved, and a whitish spore deposit.

Cap:
1-3.5(6)cm across, broadly convex with inrolled margin, becoming flat, margin remaining narrowly inrolled, broadly depressed when old and margin wavy; "white, sometimes faintly watery yellowish about disc in wet weather", faintly buff overall when old; heavily canescent [hoary], appearing finely matted-fibrillose in places under a lens, rarely rivulose [marked with river-like lines], canescence appressed when old, margin not striate, (Bigelow), 1-5cm across, broadly convex with inrolled margin, becoming flatter then broadly depressed when old with a wavy margin; whitish becoming buff-colored; "thickly covered in dense, white downy hairs", (Phillips), up to 6.5cm across, off-white with pinkish buff or pinkish brown markings on disc, sometimes staying white, (Schalkwijk-Barendsen)

Flesh:
thin, firm; white (Bigelow, Phillips), off-white (Schalkwijk-Barendsen)

Gills:
adnate to short-decurrent, close to crowded, narrow (up to 0.3cm, rarely up to 0.5cm), not forked; whitish; not interveined, (Bigelow), adnate to short-decurrent, "close to crowded, narrow"; whitish to creamy buff, (Phillips), decurrent, close, narrow; off-white to faintly pink, (Schalkwijk-Barendsen)

Stem:
1-3(4.5)cm x 0.15-0.5(1.5)cm at top, eccentric [off-center] at times, terete [round in cross-section], equal or base slightly enlarged, stem stuffed, often curved; white, finally pale buff when old; top slightly pruinose at times, innately fibrillose below, basal mycelium sparse, rhizomorphs few or absent, (Bigelow), 1-4cm x 0.2-1cm, stuffed, "base sometimes enlarged or curved"; white to pale cream or pale pinky buff; slight bloom at top, fine dense hairs in lower part, (Phillips), up to 4cm x 0.5cm, slender, tough, hollow, often bent, whitish to brownish, (Schalkwijk-Barendsen)

Odor:
not distinctive (Bigelow, Phillips), faintly or strongly aromatic, like Japanese oranges, (Schalkwijk-Barendsen)

Taste:
not distinctive (Bigelow, Phillips)

Microscopic spores:
spores 3.5-4.5(5) x 2.5-3.5(4) microns, nearly round to broadly elliptic, smooth, inamyloid, cyanophobic; basidia 4-spored, 12-23(26) x 3.5-5(6) microns; [pleurocystidia and cheilocystidia presumably absent]; clamp connections present, (Bigelow), spores 3.5-4.5 x 2.5-3.5 microns, nearly round to broadly elliptic, smooth, inamyloid, (Phillips)

Spore deposit:
"white usually, rarely faintly cream in heavy deposit" (Bigelow), white (Phillips, Schalkwijk-Barendsen)

Notes:
It was reported from BC by D.P. Lowe, and by Schalkwijk-Barendsen from Alberta. There are two collections from BC deposited at the Pacific Forestry Center (determined or confirmed by S. Redhead). Oregon State University has two collections from OR. Collections were examined by Bigelow for FL, ME, MI, NM, NY, and TN.
