Corallum colonial, ramose colonies formed from extracalicular budding, corallites occurring uniformly on all branch surfaces; coenosteum dense and striate; axial corallite present for each branch; P1 and P2 present as one crown; columella papillose.
Comparisons

Remarks
Originally described as a subgenus of Dendrophyllia and thus thought to be a dendrophylliid, after examination of the type specimen the genus was transferred to the Oculinidae by Cairns (1999). The only Recent species is described by Wells and Alderslade (1979). Approximately 10 fossil species reported by Vaughan (1900, 1919) and Szabo (2002).
