Commentaire : Corallum free-living. Each coral with usually one, centrally located mouth (monostomatous). Their outline varies from circular to slightly oval. The coralla are thick, they vary from flat to slightly arched. The length of the central fossa, measured at its bottom, is 1/5 to 2/7 of the corallum length. Maximum length of the coralla up to 25 cm. The septa are loosely packed and straight. The septa are of almost equal thickness, the primary septa are more exsert than those of the last orders. The septal margins are coarsely ornamented with lobate, rounded dentations. Their number varies from 3 to 5 per cm septum. The corallum wall is solid and granulated. The costae are almost equal in size, straight and distinct from the centre to the corallum margin. They are finely ornamentated by costal projections (spines) which are laterally flattened with sharp granulations at their margin. The spines are either single and angular-granulate or composed-lobate with several granulations at their tips. The living animal with its long tentacles resembles a sea-anemone and differ from those of any other fungiid known.
