Ircinia felix -“whitish, dark oscules, sprawling morphotype”

Notes: Thinly encrusting, sprawling to erect, with oscular mounds, ridges or branches. Surface with low conules; oscules usually on top of conical elevations or aligned on ridges. Creamy to grayish color and oscules with a dark rim. Whether the various morphotypes of what is called Ircinia felix are different species remains to be determined. This form may contain in part be what Rützler (1988) calls I. felix forma fistularis (Verrill, 1907) from Bermuda. It may also be conspecific to Ircinia repens Sandes & Pinheiro, 2014 from Brazil
