Length of fossa ≥1/10 diameter of corallum. Colony maximum diameter generally < 10 cm. Septa densely packed and (almost) equal in height, compact with distinct space in between them. Septa of lower orders thicker than adjacent septa. Septal dentations fine (>10/cm). Corallum wall solid. Costae fine, adjacent ones (almost) equal. All costae are finely ornamented with small, acute spines. Granulations on septal fringe predominantly arranged in rows, perpendicular to septal margin.
