Type locality: Mesoamerican Barrier Reef, Belize.
External morphology. Ircinia with an encrusting growth form, commonly with digitate projections, and dark gray pinacoderm ( Figure 12 View FIGURE 12 ). Conules 1–1.3 mm in height. Oscula flush or slightly raised, always black, 0.2–1 cm in diameter.
Interior morphology. Massive fascicular fibers 120–240 µm wide, heavily cored and tightly bound. Interconnecting fibers 30–50 um wide, lightly cored ( Figure 13 View FIGURE 13 ). Irciniid filaments 2–5 µm wide, terminating in spherical knobs, 5–10 µm in diameter. Cortex contains abundant inclusions of sand grains.
Ecology. This species is found on patch reefs co-inhabited by I. strobilina in shallow depths (0.5–1 m) adjacent to mangrove hammocks inhabited by I. vansoesti sp. nov. The surface is often covered with loose sand. The species commonly grows in close association with hydroids and multicellular algae.
Etymology. This species is named in honor of the sponge researcher Klaus Rützler.
Remarks. Referred to as the ‘Sp. 2’ growth form in Kelly et al. (2021).
