Psammocora nierstraszi

Horst, 1921

Colonies are massive and are primarily characterised by highly meandering valleys, often with steep walls. Corallites are distributed largely independently of the valleys. Petaloid primary septa are exsert giving the colony surface a rough appearance.

Colour: Grey, brown or cream.

Habitat: Restricted to reef habitats exposed to strong wave action.

Abundance: Rare.
