Peziza repanda, commonly known as the Palomino cup or recurved cup, is a species of fungus in the genus Peziza, family Pezizaceae.


Palamino Cup fungus in Kilmarnock, Ayrshire.

Peziza repanda can be identified by its growth on rotted wood or wood chips, its brown upper surface (at maturity) that is usually somewhat wrinkled near the center; a whitish and minutely fuzzy under surface; a round, cuplike shape when young, and a flattened-irregular shape when mature; attachment to the wood under the center of the mushroom, rather than under the whole cup; thin, brittle flesh (rather than thick and gelatinous) and smooth, elliptical spores that lack oil droplets.[1]

The cup at first is pale brown or whitish overall; cup-shaped; the under surface minutely fuzzy and the upper surface smoother; with a tiny stem-like structure. In maturity flattened-irregular or bent backwards; 6–12 cm across; the margin often splitting; upper surface brown and smooth, often "pinched" or somewhat wrinkled over the center; under surface whitish and minutely fuzzy; attached to the substrate centrally, without a stem. Odour none. Flesh brownish or pale; brittle.[1]

Peziza means a sort of mushroom without a root or stalk (not accurate for P. repanda); repanda means bent backwards.[2]

Microscopic Features: Spores 11-16 x 6-10 µm; smooth; elliptical; without oil droplets. Asci eight-spored; up to 225 x 15 µm.[1]


Well decayed logs may sport the Palamino cup fungus, which is saprobic, usually on the wood of hardwoods. Soil rich in decayed wood and occasionally that which is covered with wood chips may support Palamino cup; growing alone, gregariously, or in clusters. This member of the cup fungi is commonly found in colder weather (spring and autumn in temperate regions), but sometimes appearing in summer.[1]


P. repanda is inedible.[3]


P. repanda is widely distributed throughout America and Europe.
