Commentaire : Corallum attached. Each coral with several mouths. Corallum attached, generally thinly encrusting and following the underlying substrate. Colonies irregular in outline although smaller colonies can be circular. Calices scattered over the corallum surface without any particular arrangement, they can be more closely packed or more distant. Colony maximum diameter generally < 15 cm. Thicker and more exsert septa (five to seven) alternate with thinner septa flush with the corallum surface. The former are mostly petaloid in shape. Continuous septa going from one fossa to the other between adjacent calices can be observed in some specimens. Exsert tentacular lobes are typically found on top of thicker septa. Costae are found on the lower side of the corallum, they are small and ornamented by minute rounded granulations.
