Diagnostic characters
Small to large agaric, growing on the ground, with a white or cream to yellow spore print. Pileus white, pale, yellow, brown, grey, rarely red or pink or black, not viscid; with scales, often denser at the centre. Lamellae remote or free. Stipe central. Partial veil remnants a membranous annulus, rarely a ring zone. Spores hyaline, dextrinoid, smooth; germ pore absent. Cheilocystidia present. Lamellar trama regular. Pileipellis a trichoderm, a hymeniderm or rarely a cutis. Clamp connections present or rarely absent (apparently in L. exocarpi).
Similar genera
Clamp connections are always lacking in Leucoagaricus and Leucocoprinus. The former tends to have a smooth (not squamulose) pileus, and the latter has a pleated pileus margin. All species of Macrolepiota have large fruit-bodies and spores with a germ pore, as do most species of Chlorophyllum. In Cystoderma fruit-bodies always occur among moss, and the spores are amyloid. In Lepiota aspera the pileipellis is an epithelium.
Australian species
About ten species, with many others to be expected: Lepiota clypeolaria, L. elaiophylla (= L. xanthophylla in the sense of some authors), L. exocarpi, L. fuliginosa, L. fuscosquamea, L. lepidophora, L. micropholis, L. subcristata and L. rimosa.

Several species lacking clamp connections that were included by Grgurinovic (1997) in Lepiota (L. albofibrillosa, L. booloola and L. piterika) are excluded, pending more information on characters to allow assessment of generic position, particularly in respect of Leucogaricus and Leucocoprinus, which lack clamp connections. Two species with amyloid spores (L. cinnamomea and L. kammala) are also excluded pending confirmation of their generic placement.

Australian distribution
