<P>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.</P> <P>This page is still under construction and at this point merely serves as transportation to lower level taxa.</P>
