Commentaire : Corallum attached. Each coral with several mouths. The outline of the corals is irregularly circular. The coral shape varies from cup-shaped to foliaceous. The mouths are small, deep and numerous. Colonies can reach 1m in diameter. The septa are densely packed. They are straight between the stomata, whereas closer to the stomata, they may be slightly bent. The septa of lower order cycles are relatively thicker and more exsert than those of higher orders. The septal margins are finely ornamented with irregularly granular or slightly lobate dentations. The corallum wall is perforated and covered by granulations. The costae are more distinct in mature specimens than juvenile ones. They are straight; in some specimens they are of about the same size while in others they differ more distinctly in size. They are ornamented with spines which are either blunt and granular or elongate and echinose. The spines are covered by acute granulations pointing in various directions.
