Type locality: Bocas del Toro, Panama.
External morphology. Ircinia with a massive growth form and dark green pinacoderm ( Figure 8 View FIGURE 8 ). Body diameter 10–15 cm. Possesses low conules (1.5–1.75 mm). Oscula flush, sometimes slightly darker than the exterior of the sponge, 0.4–1.2 cm in diameter, and with a thin dark green or gray membrane.
Interior morphology. Massive fascicular fibers 110–160 µm wide, heavily cored. Interconnecting fibers 20–50 um wide, sparsely cored ( Figure 9 View FIGURE 9 ). Irciniid filaments 1–5 µm wide, terminating in spherical to tear-drop knobs measuring 6–9 µm in diameter.
Ecology. This species is found among Thalassia spp. and coral patches in shallow depths.
Etymology. The name refers to the texture imparted by the species’ low conules.
Remarks. All specimens collected had a globose growth morphology. Referred to as the ‘Massive A green’ growth form in Kelly et al. (2021).
