Description

provided by World Register of Marine Species
Massive corallum. Thamnasterioid. Radial elements are fenestrate biseptal sheets often joining, attenuated at the inner edge but with a rather constant thickness elsewhere, straight to sinuous, and rather equal. Distal edge moniliform with regular teeth corresponding to distinct trabeculae, inner edge with more or less detached trabecules, lateral faces with pennulae regularly alternating with pennulae of the opposite biseptal sheet. Pennulae with their edges turned upward and ornamented with very small teeth. Microstructure with distinct trabeculae of which the axis is rarely well marked. No palis. Radial symmetry of the septal apparatus present but generally corrupted by the dominant intracalicular increase, bilateral symmetry. marked by the curvature of septa and the distribution of junctions of inner edges of septa. Endotheca made of dissepiments often oblique in longitudinal section and putting weight on the rims of pennulae. The centre of corallite is generally occupied by a small fossa. Detached trabeculae may fuse in the center but do not form a true columella in relief. synapticulae,present in various parts of the corallite. Wall absent.
