Discomycetes is a former taxonomic class of Ascomycete fungus which contains all of the cup, sponge and brain fungi, and some club-like fungi. It includes typical cup fungi like the Sarcoscypha and the Aleuria aurantia, and fungi with fruiting bodies of more unusual shape, such as Morchella, truffles and the swamp beacon. New taxonomic and molecular data fail to support the monophyly of the Discomycetes.
A common feature of Discomycetes are the Ascus, which are typically produced on the surface of cup-like fruiting bodies. In most discomycetes, each ascus contains eight sexual that are forcibly discharged into the air when mature.
In modern classifications, the members of the obsolete class are included in Pezizomycetes, Lecanoromycetes, Leotiomycetes and Sordariomycetes.
