Color: Colonies are pale or dark brown, sometimes with purple margins and white centres. The living animal is usually brown, but may alternatively be green or ochre colored. The small tentacles are usually colorless and translucent; they are inconspicuous because of their small size.

Colonies are large, free-living, circular to oval, dome-shaped, heavily constructed and without an axial furrow. Corallites are compacted. The septa are densely packed and straight, except around the stomata, where they bend. The septa of lower orders are thicker and more protruding than those of higher orders. The septa are fenestrate; especially higher order septa, which are much perforated. Tentacular lobes are absent. The septal margins are coarsely ornamented with irregularly lobate dentations. The septal sides are thinly to densely granulated. Polyps are extended only at night.

Gonochoric, sexual, broadcast spawning.
