|---|---|---|
| D. Huang et al. 2014 | Colonial, with intracalicular budding only. Corallites monomorphic and discrete (one to three centres); monticules absent. Coenosteum costate, limited amount (includes double wall) or fused walls. Calice width medium (4–15 mm), with medium relief (3–6 mm).
Costosepta not confluent. Septa in ≥ four cycles (≥ 48 septa). Free septa regular. Septa spaced six to 11 septa per 5 mm. Costosepta equal in relative thickness. Columellae trabecular and spongy (> three threads), < 1/4 of calice width, and continuous amongst adjacent corallites. Septal (multiaxial) lobes well developed. Epitheca well developed and endotheca low−moderate (tabular). Tooth base at midcalice circular. Tooth tip at midcalice irregular; tip orientation perpendicular to septum. Tooth height medium (0.3–0.6 mm) and tooth spacing medium (0.3–1 mm), with > six teeth per septum. Granules scattered on septal face; irregular in shape. Interarea palisade. Walls formed by dominant paratheca and partial septotheca; trabeculothecal elements may be present; abortive septa absent. Thickening deposits fibrous. Costa centre clusters weak; 0.3–0.6 mm between clusters; medial lines strong. Septum centre clusters weak; 0.3– 0.5 mm between clusters; medial lines strong. Transverse crosses present. Columella centres clustered. |
