Iciligorgia schrammi Duchassaing 1870:12.
Remarks. This species, not previously recorded north of Florida, is represented in the SAB by a single specimen collected from offshore Georgia. I. schrammi is considered a deep reef species in tropical latitudes, but the examined specimen has no associated habitat data.
The specimen is dichotomously branched in one plane, and the main branches appear flattened and are 3–5 mm in width. The colony examined is relatively small, as this species tends to form very large, planar structures in southern latitudes. Because no definite base is attached to the stem it is not known if the specimen is complete. The color is light brown, but this species has been reported to be bright red in life (Cairns 1977; Humann 1993). The polyps are arranged biserially along the two edges of the flattened stem. Most polyps are visible and substantially armed with curved spindles and rods arranged as collaret and points (Figure 32D). Calyces are domelike and have eight distinct lobes. The fistulose branches (Figure 32C) distinguish this species from any other in the shallow western Atlantic.
The cortical sclerites are chiefly elongate, spiny spindles 0.5–0.6 mm in length, varying in coarseness. The medullar sclerites are long (0.5–0.7 mm), extremely slender needles that vary from smooth to slightly warty. The anthocodiae have flattened, slightly curved rods up to 0.5 mm, with a few that are a fraction of that size.
This specimen is associated with numerous small gorgonocephalid ophiuroids.
Atlantic distribution: Georgia, south Florida
to Brazil, Caribbean, 3-368 m (Deichmann, 1936; Bayer, 1961; NMNH
