Characters: Colonies are massive, flat or hemispherical. Corallites are typically inclined on the colony surface, facing downwards on hemispherical surfaces. Corallite walls have sharp rims except for colonies from very shallow water. The lower part of the wall of inclined corallites is commonly immersed, giving the upper part a hooded appearance. Septa are widely spaced and irregular in size. Paliform crowns are well developed.
Colour: Uniform yellowish-green or brown.
Similar Species: Favia speciosa and F. pallida, both of which have larger corallites with less exsert septo-costae. The inclined corallites of F. truncatus, giving a hooded appearance, usually make colonies recognisable underwater.
Habitat: Most shallow reef environments.
Abundance: Common in equatorial regions.
