If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

D. Huang et al. 2014Colonial, with intracalicular budding only. Corallites monomorphic and uniserial; monticules absent. Walls fused. Calice width small (< 4 mm), with low relief (< 3 mm). Costosepta confluent. Septa in < three cycles (< 24 septa). Free septa present but irregular. Septa
spaced six to 11 septa per 5 mm. Costosepta equal in
relative thickness. Columellae trabecular but compact (one to three threads), < 1/4 of calice width, and continuous amongst adjacent corallites. Paliform (uniaxial) lobes well developed. Epitheca absent and endotheca sparse.
Tooth base at midcalice circular. Tooth tip at midcalice
irregular; tip orientation perpendicular to septum. Tooth
height low (< 0.3 mm) and tooth spacing narrow (< 0.3 mm), with > six teeth per septum. Granules scattered on septal face; irregular in shape. Interarea palisade.
Walls formed by strong abortive septa and partial septotheca; trabeculothecal elements may be present. Thickening deposits fibrous. Costa centre clusters weak; < 0.3 mm between clusters; medial lines weak. Septum centre clusters weak; < 0.3 mm between clusters; medial
lines weak. Transverse crosses absent. Columella centres clustered.
