Similar Species: Micromussa minuta, which has larger, more rounded corallites with fewer, thicker septa. Underwater this species can readily be mistaken for a Favia with small corallites.
Habitat: Shallow reef environments.
Abundance: Uncommon.
Taxonomic Note: May be difficult to separate from other Micromussa. Placing of this species in Micromussa is tentative.
