Anthozoa - Scleractinia - Merulinidae
|D. Huang et al. 2014||Colonial, 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.
