Characters: 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.
Similar species: Oxypora glabra, which is distinguished by its lack of teeth on the costae. See also O. convoluta. May resemble Echinophyllia aspera underwater.
