Sandalolitha robusta is a plate or mushroom coral in the family Fungiidae.

[2] Sandalolitha robusta is a large, heavy colonial coral that is free living, not being attached to the substrate.

The numerous individual corallites, in which the polyps are embedded, are separate from each other.

They are bordered by alternating wide and narrow septa, calcareous ridges which bear serrated spines.

The spines on the costae, the ridges which join the septa to other corallites, are minutely spiny.
