Basidiomata medium-sized to large. Pileus 35-65 mm broad, at first hemispherical, then convex to applanate with age, sometimes depressed at disc, pileus surface covered by snuff brown, chestnut brown, purple-brown or grayish red (9B4, 9C4, 10CD4), woolly-floccose or woolly arachnoid velar remnants, usually darker at center, outer zone showing dull white to whitish background when the velar remnants vanish; margin incurved with slightly appendiculate velar remnants, often slightly lacerated; context 3-4 mm thick at pileus centre, elsewhere thin, changes from white to slightly reddening when cut or injured. Lamellae free, depressed around the stipe, broadly ventricose, bluish gray to leaden gray (19B3, 18C3) when young, becoming dark blue (19E4-7) to bluish gray (19D3-5) when mature; 3-4 tiers of lamellulae. Stipe 50-60

5-6 mm, central, cylindrical, slightly tapering towards the base, floccose-squamulose all over the stipe, often vanish from handling or rain, with lighter shade of the pileus color, fistulose; stipe context slightly reddening when cut or injured. Annulus delicate, fugacious. Odor and taste unknown.
