Commentaire : Corallum attached. Each coral with several mouths. Colonies encrusting. The corallum outline is irregularly round, depending on the relief and shape of the substratum. The margin is free from the substratum. The primary stoma is relatively large. The smaller secondary stomata are densely arranged around it. Colony maximum diameter generally < 15 cm. The septa are very densely packed and vary from straight to wrinkled. The septa of low order cycles are thick, whereas those of higher orders are thin. The septa of lowest orders protrude more than those of other orders. The septal margins are finely ornamented with dentations which are either irregularly granular or ravel-shaped. The wall is solid and covered by granulations. The indistinct costae are straight and bear numerous fine spines.
