Axial corallites: Outer diameter 2.1 mm; inner diameter 0.8 mm; tubular and elongated; primary and secondary septa are clearly defined and plate-like.

Radial corallites: Similar, dimidiate to cochleariform with no upper wall; lower lip is flaring or eXtended upward; septal development is rudimentary, usually with incomplete cycles, mainly with directive septa; radial corallites are arranged in a neat rosette around axial corallite.

Coenosteum: Neatly costate on corallites and reticulate with spinules scattered or in lines in between.
