Diagnostic characters
Small to medium agaric, growing on wood, with a white or cream spore print. Pileus typically pink, but it can be white or pale, or with darker brown or purple tones, viscid. Lamellae adnexed, adnate or subdecurrent. Stipe excentric, lateral or absent. Partial veil remnants absent. Spores hyaline, amyloid, smooth; germ pore absent. Cheilocystidia present or absent. Lamellar trama regular or interwoven. Pileipellis a cutis or a trichoderm. Clamp connections present.
Similar genera
Panellus ligulatus has a dry pileus and non-amyloid spores, while in P. stipticus the pileus is pale brown rather than pink, and the surface is dry or not very viscid. In Hohenbuehelia the pileus can be viscid, but it is brown or grey. In addition, spores are non-amyloid, and there are thick-walled cystidia in the hymenium. All other pleurotoid agarics (see Pleurotus) lack amyloid spores, except Lentinellus, where the lamellae edges are serrate and the spores are ornamented.
