Diagnostic characters
Medium-sized agaric, growing on the ground or rarely on wood, with a pinkish brown spore print. Pileus pale, brown or grey, not viscid. Lamellae sinuate or notched, subdecurrent or decurrent. Stipe central, rarely excentric or lateral. Partial veil remnants absent. Spores angular in end view but not distinctly in side view, hyaline or pale, rarely brown, non-amyloid, warty; germ pore absent. Cheilocystidia present or absent. Lamellar trama regular. Pileipellis a cutis. Clamp connections absent (in all Australian species), rarely present.
Similar genera
Entoloma has spores that are angular in all views, and a wider range of fruit-body colours than in Clitopilus morphogroup Rhodocybe. In the field the more robust species of morphogroup Rhodocybe are difficult to distinguish from Lepista, but that genus has warty spores that are not angular in any view, and clamp connections are present. In Hebeloma the pileus is not viscid, spores are pale to yellow-brown, warty and not angular, and clamp connections are present.
Australian species
Eleven species belong to morphogroup Rhodocybe, most until recently placed in Rhodocybe as a separate genus: C. acerbus (= R. amara), C. conchatus, C. fuligineus, C. lateritius, C. pallidogriseus, C. pseudopiperitus, C. radicatus, C. reticulatus and C. tasmanicus, with R. cyathoidea and R. gracilenta yet to be transferred into Clitopilus.
Australian distribution
W.A., S.A., Qld, N.S.W., Vic. and Tas. (and probably also N.T.).
Habitat
In native forests.
Substrate
On the ground, sometimes on bare ground (such as trackside banks or mounds of clay), or occasionally on wood.
Trophic status
Saprotrophic.
