The length of the fossa is 1/12 to 1/6 of the corallum length. Corallum maximum diameter generally < 10 cm. The septa are densely packed and straight. They are unequal in thickness and in height. Septal dentations coarse (≤10/cm). Corallum wall solid. The costae are almost equal in size, straight and prominent near the corallum margin. They are ornamented.
