Calyces are tiny, almost pin prick size, and arranged in rows along ridges that radiate from the center of a growing plate to the plates margin.
Calyces range from 10 to 15 mm in diameter, are somewhat irregular in outline and their rims show a tooth-like appearance that is caused by the incomplete development of one cycle of septa.
Calycal diameter ranges 2 to 5 mm and the calyces are clearly separated and slightly protruding from the coral surface.
