Exclusively colonial corals resulting from extratentacular budding resulting in dendroid, plocoid, or ramose colonies. Corallites externally thickened with extensive non-costate, dense coenosteum. Septa usually highly exsert, composed of one fan system of simple trabeculae; septal margins only minutely dentate. Endothecal dissepiments thin or replaced with dense stereome.
