Diagnostic characters
Small agaric, growing on litter or wood, with a rusty brown spore print. Pileus yellow to brown, not viscid, not hygrophanous. Lamellae adnate or adnexed. Stipe lateral or excentric. Partial veil remnants a ring zone or membranous annulus. Spores orange-brown, smooth; germ pore absent. Cheilocystidia present. Lamellar trama regular. Pileipellis a cutis or trichoderm with branched terminal elements. Clamp connections present.
Similar genera
Among genera with an excentric to lateral stipe and rusty-brown spore print that grow on wood, Pleuroflammula praestans is distinct due to the combination of a dry, non-translucent-striate pileus, a partial veil and smooth spores. In addition, fragments of lamellae mounted in 3% KOH release yellow pigment. Gymnopilus has rough spores, and its fruit-bodies are often large. Smooth-spored species of Galerina have a hygrophanous, translucent-striate pileus that lacks scales. In Pholiota the pileus is viscid or glutinous and the spores have a germ pore. Pleuroflammula praestans is distinguished from smooth-spored species of Crepidotus by the presence of a veil that leaves an annulus or ring-zone.
