Description Solitary corallum with a subcircular calice, proximally arched. Wrinkled epitheca, but discrete costae. Radial elements are compact, unequal, free (minor) and anastomosed (major) sinuous septa (or costosepta ?). Thickness constant to variable, bicuneiform to attenuated toward the inner edge. Distal edge smooth, steep near the wall, lateral faces with very small and numerous regularly distributed granules. Occasionally a detached tooth on the inner edge. No pali. Microstructure non trabecular with laminar layers. Hexameral symmetry present with disctinct categories of size order in septa. Bilateral symmetry marked by the elongation of the central fossa and the proximo-distal curvature of the corallum. Endotheca made of tabuloid dissepiments steeply inclined near the wall. Columella parietal. Synapticules absent. Paratheca peripheral, cutting, in continuity with non trabecular septa. [details]
