Colonies are composed of basal plates with short branches of irregularly fused corallites. Corallites are 3-4 millimetres diameter and are thick walled. Those on basal plates are up to 8 millimetres exsert and are strongly inclined. Septa are in four orders and may fuse according to Pourtalès plan. Primary septa have paliform lobes. Columellae are compact. Costae are in two orders and are mostly smooth.
