Description: Basidiomata clitocyboid, omphaloid, or pleurotoid, small to large. Pileus convex, plano-convex, plano-concave, or deeply concave; surface white, gray, brown, or dark grayish brown, rarely reddish brown; surface glabrous or tomentose, sericeous or velvety, sometimes venose, viscid or hygrophanous when wet or pruinose when dry; margin incurved or undulate. Lamellae decurrent, whitish to pinkish. Stipe absent or central, eccentric to lateral, usually concolorous with pileus. Odor none or farinaceous. Basidiospores flesh pink or brownish pink in deposit, thin- to slightly thick-walled (<0.5 μm), inamyloid, angled in polar view with 4–12 distinct longitudinal ridges.
