The pale, cup-shaped ascocarps grow to 1–6 centimetres (122+12 inches) in width and often form clusters. The spore print is white.[2]

Similar species


The species is difficult to identify from other Peziza without microscopy.[2] Species with purplish tints, particularly within the cup, have been split off into Geoscypha. Similar species may also be found in the Tarzetta and Jafnea genera, as well as purplish species of Legaliana and Phylloscypha.[2]

Distribution and habitat


The species can be found year-round throughout North America; usually within its December–April season on the West Coast.[2] It is common in Europe, with scattered records in other parts of the world.[citation needed] It is found on nutrient-rich soils, e.g. manure and compost.[2]



The species is considered poisonous.[3]
