Description

englanti
)
tarjonnut World Register of Marine Species
'Coral neatly turbinate, with a narrow, somewhat expanded base. Outside of wall covered almost to the edge with a thin closely adherent epitheca, through which the costæ are distinctly perceptible. Costæ crowded, perfectly equal, prominent, minutely denticulate. Calicle circular, deep. Edges of septa with crowded, narrow, subequal teeth. Columella very small, rounded in outline, coarsely trabecular.' (Brüggemann, 1877: 310)

tarjonnut World Register of Marine Species
Colonial, but may be solitary in Homophyllia australis; colonies submassive or massive. Budding intracalicular, and may also be extracalicular. Corallites typically monomorphic; discrete. Monticules absent. Walls fused. Calice width large (> 15 mm), with high relief (> 6 mm). Costosepta mostly confluent. Septa in = four cycles (= 48 septa). Free septa irregular. Septa spaced 6–11 septa per 5 mm. Costosepta unequal in relative thickness. Columellae trabecular and spongy (> three threads), < 1/4 of calice width, and discontinuous among adjacent corallites with lamellar linkage. Internal lobes usually absent. Epitheca well developed. Endotheca low-moderate (tabular). Tooth base at midcalice elliptical-parallel. Tooth tip orientation parallel. Teeth tall (> 0.6 mm); widely spaced (> 1 mm), with > six teeth per septum. Tooth shape equal between first and third order septa. Tooth size equal between wall and septum, but the teeth at midcalice may be larger than those at the columellar end of the septum. Granules distributed uniformly on septal face; weak (rounded). Interarea smooth. Walls formed by dominant paratheca and partial septotheca. Thickening deposits in concentric rings with extensive stereome. Costa centre clusters strong; > 0.6 mm between clusters; medial lines weak. Septum centre clusters weak; > 0.5 mm between clusters; medial lines weak.
