Six closely related species of the genus Peziza are treated: P. ampliata, P. crassipes, P. cerea, P. micropus, P. varia, and P. arvernensis. These species are characterized by rather large, mostly ochre-yellow to ochre-brown apothecia, and are found on rotten wood, plant remains, or soil. Descriptions are based on ca. 150 specimens from different localities (mainly PR herbarium). Diagnostic characters include apothecial structure, spore size, spore ornamentation, and ecology.
