The toadstool groper is a solid-bodied species, with no gap between the two dorsal fins the first of which is long and low and the second high and rounded. The tail is slightly convex. The operculum has a distinct point.
Colouration is orange-red with some paler patches and is uniformly covered on both body and fins with close-set white dots, resembling a toadstool.
It lives in crevices and caves of rocky reef areas during the day, moving out to feed during the hours of darkness.
