Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R.C. Baron-Szabo 2021 | Colony massive, meandroid. Budding intracalicular. Individual corallites subdistinct to indistinct, rarely isolated (cerioid to cerio-plocoid), forming long or short calicinal series, simple and ramifying, separated by
tholiform collines, and ?ambulacra. Septa compact, distal margin finely dentate, finely granulated to strongly beaded laterally. Axial ends of septa rhopaloid (older generations) and claviform to cuneiform (younger generations). Costae generally short or absent. Auriculae and lonsdaleoid septa present. Columella absent but trabecular extensions of axial ends of septa may form a pseudo-columella. Intertrabecular distance ranging between 60 and 200 μm. Wall septothecal and parathecal. Endothecal dissepiments arched, raised in the vicinity of the wall |
