Diagnosis. Colonial. Gemmation predominantly extracalicinal, rarely intracalicinal. Polyps generally circular, wall parathecal or septothecal (latter often thickened by stereozone). Radial elements (septa or costosepta) always compact and consisting of simple trabeculae, arranged in a single series or in a divergent system. Distal septal margins have very delicate denticles, sometimes subobsolete or made of granulae. Lateral septal surfaces ornamented with granulae, which can be very delicate and are aligned parallel to the distal margin. Auriculae present in some groups (e.g., nominatform Stylina ), generally before 3 rd cycle septa or younger. Endotheca present, generally abundant and vesicular, sometimes tabulate. Peritheca nearly always present.
