Colony plocoid, encrusting on dead coral, its growing edge closely adhering to substratum, leaving very narrow free portion covered with epitheca visible here and there.
Upper surface high convex, without prominent irregularities disturbing its planeness.
Corallites unequal in size, mostly subcircular with a number of oval, pentagonal and distorted forms. Big subcircular corallite 11 x 10 mm in diameter; a polygonal one 10 x 8 mm; an oval one 11 x 8 mm; many smaller ones mixed with big ones. Calicinal theca thick (1.5 mm) level with general surface, only exsert portions of septa give slight prominence to corallites. Calicinal fossa funnel-shape, 2-3 mm deep. Extra and intratentacular budding present.
Septa around 24, sloping towards calicinal center from thecal region, thinning gradually as they do so, all slightly exsert. Primaries not uniform – 3 or 4 of them among big corallites stand very prominently over the others; secondaries likewise unequal in height, extending to calicinal center; tertiaries do not reach calicinal center, some join secondaries at their lower ends. Few quaternaries present but limited to thecal summit only or slightly extended into fossa as very low ridges against wall. Septal edge produces regularly arranged tall spatulate teeth which gradually become lower and blunt pointed towards calicinal center; without paliform lobes. Septal surface smooth or slightly granulate.
Perithecal area very narrow, deep groove (often occupied by tube of polychaete worm), bridged across by costae from adjoining corallites, with or without notches marking their demarcation lines. Costal spines prominent, also spatulate.
Columella absent or represented by one or two low papillae only.
