Characters: Colonies are composed of foliose to encrusting unifacial laminae which may become highly contorted forming hollow columns or tubes. A central corallite may be distinguishable. Corallites become more widely spaced towards the colony perimeter. They are irregular and usually outwardly inclined. Long and short septo-costae strongly alternate and are interlinked in complex patterns.
Colour: Dull grey, brown or green, usually with white margins.
Similar Species: Leptoseris hawaiiensis, which is distinguished by having deep, rounded corallites and a smooth coenosteum. See also L. solida and L. striata, which do not have strongly inclined corallites.
Habitat: Usually found on vertical or overhung walls in deeper water.
Abundance: Usually uncommon.
Taxonomic Note: A species complex and easily confused with Leptoseris solida.
