The fruiting body appears from spring to early autumn as a deep cup split down one side and elongated at the other, up to 10 centimetres (4 inches) tall.[1] It is yellow to orangish or slightly pinkish. White hairs cover the outside, while the inside is smooth or rippled.[1][2]

Similar species include Guepinia helvelloides, others of the genus Otidea, as well as some of Pezizaceae family.[2]

Otidea onotica occurs in Europe and North America, singly or in small groups[2] on the soil of deciduous woodland, most often with beech trees.
