This is a thickly encrusting sponge with a very firm texture, growing in loosely attached patches up to 7 cm across. The granular outer layer is brilliant yellow-orange with a rather darker interior carrying many symbiont foraminifera. It is often infested with the parasitic amphipod Polycheria antarctica.
