Pileus 2 – 9 cm in diam., nearly applanate, reniform or convex, soon flattened, center slightly depressed when aged, margin incurved at first and then usually irregularly undulate when mature or aged; surface felted to glabrous or subvelutinous and subviscid when wet, brown (6 E 6 – 8) to yellowish brown (5 E 4 – 5) with dark brown (6 F 4 – 8) or grayish brown (6 F 2 – 3) tinge in the center, much paler towards margin.
