Characters: Polyps are circular. Septa are in two distinct orders, those of the first order being very exsert, straight and thin. All septa have fine teeth. Tentacles, which are sometimes bifurcated, are commonly extended during the day.
Colour: Usually olive-green with tiny but conspicuous violet tentacle tips.
Similar Species: The exsert alternating septa with fine teeth are distinctive.
Habitat: Reef slopes and lagoons.
Abundance: Uncommon.
Taxonomic Note: Called Heliofungia fralinae by Gittenberger, Reijnen and Hoeksema (2011) from molecular data, but this species has little in common with Heliofungia actiniformis. Heliofungia is distinctively monospecific.
