Colonial, massive, plocoid. Budding mainly extracalicular, sometimes intracalicular of various kinds (such as the fission). Costosepta compact, arranged radially or irregularly radially to bilaterally. Development of granules on septal flanks by divergent trabeculae best described by MORYCOWA (1971, p. 95–98). Columella generally lamellar, or rarely made of a small number of short lamellar segments. Endothecal dissepiments vesicular or tabular, sparse. Pali or paliform structures before 1st and 2nd cycle septa irregularly present. Wall parasynapticulothecal and (para-)septothecal, with pores in places. Perithecal wall made of dissepiments and synapticulae.
