The Pezizaceae (commonly referred to as cup fungi) are a family of fungi in the Ascomycota which produce mushrooms that tend to grow in the shape of a "cup".

Spores are formed on the inner surface of the fruit body (ascoma).

Additionally, the curvature enables wind currents to blow the spores out in a different manner than in most agarics and boletes.

For example, the orange peel fungus (Aleuria aurantia) resembles a discarded orange rind.

According to one 2008 estimate, the family contains 31 genera and 230 species.
