Diagnostic characters
Small agaric, growing on the ground with white spore print. Pileus typically pale, or yellow or brown, rarely red or pink, not viscid. Lamellae adnate, subdecurrent or decurrent, distant. Stipe central. Partial veil remnants absent. Spores globose to broadly ellipsoid, hyaline, non-amyloid, smooth; germ pore absent. Cheilocystidia present or absent. Lamellar trama regular. Pileipellis a hymeniderm or an epithelium. Clamp connections present or absent (in both Australian species).
Similar genera
Camarophyllopsis often has subdecurrent or decurrent lamellae and then it resembles omphalinoid agarics such as Lichenomphalia and Loreleia. However, it differs from these and genera of the Hygrophoraceae (Hygrocybe and Humidicutis) by the pileipellis which is a hymeniderm or epithelium, and composed of globose to pyriform elements. Both Australian species of Camarophyllopsis have subglobose spores, which are not often present in white-spored agarics with no veil and smooth, non-amyloid spores. Such spores are completely absent in agarics with a regular lamellar trama and a pileipellis which is a hymeniderm or epithelium. The only exception is Oudemansiella (other), which has a pseudorhiza.
