External morphology. Thinly encrusting 4–60 cm 2 areas; dry feeling (non-mucous). Live color is deep red, dull red, greenish orange to ochre.
Skeleton structure. Interconnected spicule tracts (including styles and tylostyles), ending in reticulation and some brushes at the sponge surface. Acanthostyles occur mainly near the base.
Spicules. Styles, many subtylote: 220–360 x 5–9 (324 x 7) Μm; (sub-)tylostyles I (some with microspined heads): 220–330 x 3–4 (262 x 4) Μm; (sub-)tylostyles II: 80–160 x 2–3 (122 x 2) Μm some with microspined heads); acanthostyles: 38– 60 x 5–10 (48 x 6) Μm; regular toxas: 45–100 (67) Μm, all about 1 Μm thick; rhaphidiform toxas: 200–275 (160) Μm, all <1–1 Μm thick; palmate isochaelas in two size categories, I: 8–13 (12) Μm and II: 3–8 (5) Μm, the latter mostly twisted.
Ecology. Common on the lower surfaces of coral rubble; also found on concrete pillars under a boat dock, and on the ceiling of a small cave on the forereef; 1– 18 m.
Distribution. Forida, Bahamas, Gulf of Mexico, and throughout the Caribbean.
Comments. Lobate, ramose, and flabellate specimens are known from non-cryptic habitats in mangroves and on reefs (van Soest, 1984a). The synonymy of this species has been clarified in a recent revision by van Soest et al. (2013a).
