- Notes: Previously placed under genus Xestospongia. In The western and northern Caribbean and the Bahamas, this species occurs as low, dark brown to black tubes, orten partly buried or with a basal mass widely filling crevices from which low tubes protrude. The surface may be riddled with holes. In the southern Caribbean it occurs as long, dark brown, smooth tubes, single or in groups. Spicules are oxea with ends a little rounded, 140-175 x 3.1-5 µm in the Bahamas. Crevice-filling specimens may be confused with Calyx podatypa (de Laubenfels, 1934) (pictured herein), which are brown, more crumbly, and have smaller and thinner spicules (92-122 x up to 2 µm.
