Septa in some genera connected to each other. Septal distal margins smooth, lateral faces with fine thorns, inner margins often swollen or T-shaped. Lonsdaleoid septa very rare. Main septum absent. Microstructure of very small trabeculae, only marked by a dark line. The costae are made by medium-sized trabeculae that result in granulated costal surfaces. Synapticulae and pali absent. Columella present or absent. Endotheca mostly present. Marginarium absent. Wall generally present, septothecal. Coenosteum present in some genera. Budding varies.
