Diagnosis

Colonies lobate, digitate or encrusting, normally with a whitish outer layer and magenta inner layer, but completely magenta or white colonies also occur. Polyps monomorphic, retractile, and without sclerites. Protruding false calyces appear in varying degrees of prominence or are not present at all. Surface layer with straight or curved spindles. Medulla with sclerites shaped like those of the surface layer but larger and coarser, and with additional branching sclerites, which can be fused. Zooxanthellate.
Only spindles present in coenenchyme ; Many spindles with pointed ends in coenenchyme, all sclerites magenta
Top of the calyces with some rods, 0.10–0.15 mm long. ; Cortex sclerites up to 1 mm long ; sclerites slightly shorter, up to 0.70 mm long
