Corallum fasciculate. Corallites rounded-tetragonal, 0.7—1.25 mm in diameter; placed in irregular groups, in short rows, and sometimes also in a dispersed way, not touching each other. Walls thin. The four cuneate septa, sometimes penetrating to the centre of corallites, are always visible. The secondary septa are seldom observed.
