Description. Sponge that lives in association with the calcareous algae Jania adherens J. V. Lamouroux, 1816, it is massive and has mounds that resemble small volcanoes. The oscula are circular and mostly oval, 2 – 6 mm in diameter (Figure 3 A). The surface is rough, not very compressible and brittle. The ectosome is regular, tangential, made up of single oxeas that are joined at each end by spongin (Figure 3 D). The choanosome is more difficult to differentiate due to the ramifications of the calcareous algae, but a reticulate network of spicule lines is distinguished (Figure 3 E). It has robust oxeas, with a slight curve in the middle and sharp ends (168.5 x 6.7 µm), the microsclere are C-shaped sigmas (20.4 µm) (Figure 3 B – C). Ecological notes. The species was found over rocks and calcareous algae from 12 to 16 m deep.
