Colony uniserial or pluriserial. If pluriserial, encrusting or erect; unilaminar, bilaminar foliaceous or plurilaminar by self overgrowth. Zooids large and convex. Frontal wall extensive, calcified, rugose and perforate by pseudopores which serve as opesiules. Orifice D-shaped, with a distal oral shelf (vestibular arch) under the operculum. Operculum calcified and thick. Heterozooidal gynozooids may be present. Ovicell subimmersed usually recumbent, the zooid it overlies being restricted, in many cases having no room to develop either a polypide, or orifice and operculum and thus is a kenozooid. The ovicell is closed by the operculum of the maternal zooid, which has two positions of closure: an upper one for the ovicell and, below this, a position for the zooid. Avicularia may exist, similar in size and aspect to an autozooid, but differing in their orifices that are roughly square or rectangular in shape, usually with external denticles in their distal edge and acute teeth directed downwards, not visible when the orifice is closed. Oral spines present either in the avicularia, the autozooids, or both. If both zooidal types have oral spines, those of the avicularia are usually longer and thicker. Avicularia with oral spines have always one spine more than the mandibles have denticles. Interzooidal communication by basal pore chambers (dietellae), usually three (one distal and two distolateral) produced by each zooid, sometimes divided into secondary chambers.
