DESCRIPTION

Solitary coral cylindrical to conical, circular to slightly elliptical in outline. Radial elements are straight or curved, free, compact, bicuneiform costosepta with often rhopaloid inner edges. The septal apparatus is regular, organized in 3 or 4 distinct size orders. Lateral faces are smooth or finely granulated and there are some vestiges of a wavy mid-septal line. Endotheca made of numerous vesicular dissepiments distributed in all the interseptal space on which some lonsdaleoid septa can appear. No columella but a constricted, elongated fossa that defines a bilateral symmetry superimposed to the radial arrangement.An epicostal epitheca s.l. covers the external parts of the corallum. Calicular diameter: 22 to 57 mm – Number of septa: 51 to 90? – Septal density: 3 to 5 per 5 mm.
