Chalice Coral - Small

Colonies are thin, encrusting or laminar plates. They may become greatly thickened in turbulent environments.

Corallites may be fine and delicate on thin laminae to grossly thickened on submassive parts of the same colony. Costae are always toothed.

Colour: Usually pale brown or greenish, either uniform or with green, white or red oral discs. Some have amazing colouration and these enter the Ultra category due to the colour morphs. Similar species: Oxypora glabra, Echinopora, Mycedium which are different genius but all called under the name of Chalice Corals.
