Commentaire : Corallum attached. Each coral with several mouths. The corallum outline varies from regularly circular (mostly in small specimens) to undulating or folded. Colony maximum diameter generally < 10 cm. The densely packed septa are straight near the centre, but wavy and diverging/converging towards the periphery. The septa of lower orders are high and very thick, those of higher orders are low and thin. The septal margins are either frayed or finely dentated. Corallum wall solid and not granulated. Costae are only visible where the corallum periphery extends beyound the substratum. The costae are poorly developed and nearly of equal size. They are ornamented by simple granular spines.
