- COTW – Vol 2 p. 300-303
Currently found in the Indo-Pacific.
Halomitra form free-living, circular colonies of up to 50cm diameter, which are strongly domed. Colonies are found in protected areas and are uncommon to rare.
The corallites are clearly differentiated, widely spaced, and incline towards the edge of the colony. The septocostae may meet at right angles between corallites. The arrangement of septa running down the upper surface and costae running along the lower surface are characteristic of the Fungiidae. Check out the Fungiidae training video for more information.

The Coral Finder lists Halomitra in one key group with Sandalolitha being a candidate for confusion.
Similar genera to Halomitra (Coral Finder p25)
Halomitra can be confused with Sandalolitha, but may be easily separated by the widely spaced corallites, and the groups of thin septa that meet at right angles, which are characteristic of Halomitra. Sandalolitha has closer packed corallites, thicker septa and a heavier skeletal construction.
