Ircinia felix -“brown, dark oscules, massive morphotype”

Notes: Massive in shape, usually round. Oscules usually spread over the surface, sometimes in groups. Surface conulose. Its color can be dark brown to light brown to grayish, with characteristic darker oscular rims. Whether the various morphotypes of what is called Ircinia felix are different species remains to be determined. This form may be what Rützler (1988) calls I. felix forma felix in Bermuda.
