Diagnostic characters
Small to medium agaric, growing on the ground, litter, mulch or dung, with a rusty to ochre-brown spore print. Pileus pale or brown, rarely white, moist, rarely viscid, hygrophanous. Lamellae adnexed or adnate, rarely free. Stipe central. Partial veil remnants absent. Spores yellow-brown or reddish brown, smooth; germ pore narrow or broad, rarely absent. Cheilocystidia present, lecythiform (widest below, with a capitate apex); pleurocystidia absent. Lamellar trama regular. Pileipellis a hymeniderm. Clamp connections present or absent.
Similar genera
Among brown-spored agarics, Conocybe is rather similar macroscopically to smaller species of Cortinarius and to Galerina and Tubaria, which differ by having a pileipellis that is a cutis or a trichoderm. Spores are usually warty in Cortinarius and Galerina (with a plage in Galerina). Cortinarius, Galerina and Tubaria also differ in having a cobwebby (Cortinarius) to membranous (some Galerina and Tubaria) partial veil. In addition, Cortinarius and Galerina do not grow on dung, and the latter is only occasionally found in mulch. Among brown-spored agarics a hymeniderm is otherwise found only in Bolbitius (which has a pleated, viscid pileus that rapidly collapses and is often bright yellow), and Agrocybe (which can have an annulus and/or pleurocystidia, and a pileus that is not translucent-striate). In Pholiotina an annulus or ring zone (or else an appendiculate pileus margin) is present in the species known from Australia, and where lecythiform (capitate) cystidia are present, the capitate apex is not abruptly seated on a short, distinct neck, as in Conocybe.
