Dimensions of skeletal elements. Great diameter of corallites: 1–1.8 mm, up to around 3 mm when wall exceptionally thick (around 0.5 mm or larger); great diameter of corallites (lumen): 0.8–1.8 mm; septa/corallite: 1–12; distance of corallite centers: 1.2– 3 mm, in areas of intense budding around 1 mm.

Description. Small submassive to subramose colony; corallites plocoid to cerio-plocoid, cerioid when crowded, oval to irregularly shaped in outline, regularly disposed over the colony; septa arranged bilaterally; in some corallites, septal arrangement in 3 systems present; one major septum present; remaining septa highly irregularly developed including very thin and half the length of major septum, or very short, spine-like; axial end of major septum rhopaloid or cuneiform; costae short and thin, up to twice the number of septa.
