Description:Pileus 10–25 mm diam, obtusely conical to paraboloid, expanding with age; the margin slightly inflexed initially, edges crisped and occasionally eroding or splitting with age, pellucid-striate when moist, striate to sulcate in age; surface dull, dry, covered with a hoary bloom when fresh, glabrescent; the disc violet-brown (10–11F5–7) to deep grayish red or grayish violet (12-13E5-6) initially, becoming more grayish- to brownish red/violet with age, the margin paler, grayish red (9C3) to pale reddish brown (9D5–6), becoming grayish pink with moisture loss. Context thin, white. Lamellae ascending-adnate, with or without a short decurrent tooth, subdistant with 1 or more series of lamellulae (18–20 reaching the stipe), narrow to moderately broad (up to 2.5 mm); white to buff, often with pinkish tones, the edges violet to violet-brown (11–12D6), rarely concolorous with lamellae sides. Stipe 25–72 — 1.5–3 mm, central, terete to somewhat flattened and once-cleft, hollow; surface dull to polished, dry, the apex white pruinose initially, glabrescent; white with pink tones or pinkish gray (9-11C3) overall when young, in age the apex remaining pinkish gray with the base becoming gray to brownish gray; the base sparsely covered with short, white fibrils. Odor mild or musty. Taste mild to unpleasant.
Basidiospores 9.6–12.2(–12.6) — (5.6–)6.2–7.7(–8.1) µm [x = 11.0 ± 0.9 — 6.8 ± 0.5 µm, Q = 1.4–1.9, Qm = 1.6 ±0.1, n = 50 spores], ellipsoid to broadly ellipsoid, smooth, thin-walled, amyloid. Basidia 27–37 — 7.2–9.6(–11.3) µm, clavate, 4-spored, clamped, sterigmata up to 8.8 µm in length; basidioles clavate. Cheilocystidia 24–59 — 7–16 µm, subcylindrical, irregular-lageniform or fusoid-ventricose, apically giving rise to one or several, short to long, cylindrical to sinuous, simple or rarely branched excrescences, 4.0–41.6 — 2.4–4.0 µm; thin-walled, filled with brownish violet, granular contents when mounted in water or Melzer's reagent; forming a sterile lamellar edge. Pleurocystidia absent. Pileipellis a cutis; hyphae 2.4–4.8(–8.1) µm diam, clamped, thin-walled, smooth or covered with coarse, inflated or more rarely cylindrical, often furcate excrescences, 2.0–15.2 (–23) — 1.6–6.4 µm diam; hyphae filled with copious oily droplets, or with reddish brown, granular contents when mounted in water or Melzer's reagent. Hypodermium composed of inflated, elongate cells, brownish-vinescent in Melzer's reagent. Pileus and lamellar trama similar to hypodermium. Stipe tissues monomitic, parallel, brownish-vinescent in Melzer's reagent; cortical hyphae 2.0–3.2 µm diam, clamped, thin-walled, covered with scattered to densely spaced, lump-like to strikingly inflated, coarse excrescences, 3.2–22 — 3.2–9.6 µm; terminal cells repent, up to 8.8 µm diam, covered with excrescences similar to those of the cortical hyphae.
Cespitose on wood of Pseudotsuga menziesii (Mirbel) Franco, and possibly that of Arctostaphylos glandulosa Eastw., North and Central Coast Ranges.
