Algae are olive green in color and measure to 4.0 cm in height. Multiple stipes, to 12 mm in length and from 1.6 to 2.6 mm in diameter, arise from basal rhizoidal masses. The blades are zonate and either fan- or funnel- shaped, measuring 3.0 cm high and to 3.5 cm broad when fan-shaped, and to 3.5 mm across when funnelshaped. Blades commonly anastomose with other blades from the same holdfast. Blades are thin, measuring only to a maximum of 1.0 mm in thickness, becoming almost monosiphonous at the blade margin. Innermost medullary filaments are cylindrical, measuring to 19 µm in diameter. Medullary filaments are constricted immediately distal to the wide-angled dichotomies. The larger medullary filaments are occasionally briefly moniliform for short distances. Filaments of the blade decrease in diameter, 6.0-8.0 µm, and becoming tortuous towards the surface. Siphon apices are obtuse.
Type locality: Lee Stocking Island (Exuma Chain), Bahamas (23°46.78'N and 76°05.00'W) (Ballantine & Aponte 2003: 121). Holotype: D.L. Ballantine 4917; 31.viii.1994; 61 m. US Algae 204257 (Ballantine & Aponte 2003: 121).
