Description:Description — Pileus 1.5–3 cm broad, plano-convex or campanulate at first, expanding to applanate with a central depression, not hygrophanous, at first brown (6D2–6E2), becoming pale pinkish brown or yellow-brown (7B2–7C2), entirely tomentose at first, becoming squamulose with age, denser at center, squamules brownish, margin not striate or obscurely striate, with a visible dark blue line along the margin. Lamellae adnexed to short decurrent, moderately crowded, thin, up to 3 mm broad, at first white, becoming pink, with contrasting, blue-black, serrulate edge, with three tiers of lamellulae. Stipe 50–65 mm in length, 1–3 mm in diam., cylindrical, slender, rather long, bluish gray (20B1–20B2), hollow, covered with very minute fibrils, apex sometimes pruinose, base with white or grayish tomentum. Context grayish white, 0.5 mm height at disc. Taste and odor not distinctive. Basidiospores (8) 8.5–10.5(11) × 6.5–8 µm (x = 9.2 ± 0.3 × 7.3 ± 0.3 µm), Q = 1.15–1.4 (Q = 1.3 ± 0.05), heterodiameteric, thick-walled, 5–6-angled in profile view. Basidia 25–40 × 9–13 µm, clavate, 4-spored. Lamellar edge entirely sterile, with dense clusters of cheilocystidia. Cheilocystidia 30–80 × 5–13 µm, cylindrical to subclavate, rather thin-walled, often agglutinated and clustered forming a sterile strand, often collapsed, with intense blue, intracellular pigment in water, colorless in KOH. Pleurocystidia absent. Pileipellis a cutis with transition to a trichoderm, consisting of cylindrical hyphae (60–280 × 5–25 µm), with scattered or clustered suberect, cylindrical to cylindrical-clavate terminal cells (80–200 × 12–20 µm), with prominent violaceous or pale brownish, intracellular pigment. Stipitipellis a cutis with some clavate terminal cells (5–9 µm in diam.) erect, thin-walled, colorless. Clamp connections absent in all tissues.
