Diagnosis Colonial; colony formation by intra- and extratentacular budding. Basal epitheca present. Corallites synapticulothecate. Septa relatively few, composed of one system of 3 to 5 nearly vertical simple trabeculae, with numerous pores, laterally united by simple synapticulae, the innermost trabeculae often differentiated as paliform lobes. Septocostae often scarcely distinguishable, even absent when the distal ends of the septa bifurcate and become lost in a coenenchyme composed of discontinuous vertical trabeculae united horizontally by simple synapticulae; coenenchyme spinose or vermiculate on the surface. Columella absent or composed of one or more trabecular pillars. Endotheca thin, subtabulate. [details]
