Martens) B0rgesen 1934: 10, gs. 1,2 Thallus: filamentous, coarse, stiff, loose, forming pad- like cushions, to 10 cm diam., 5 cm thick, glossy green; branching generally unilateral. Filament cells cylindrical, () mm diam., 2-10 or more diameters long. Branchlets cylindrical, with no or little taper, originating from upper ends of parent cells; wall formation basal to main lament.

Phylum Chlorophyta Class Ulvophyceae Order Cladophorales Family Anadyomenaceae DichOthriX fudCOla (Kutzing) Bornet & Flahault 1 886: 379 Thallus: forming small erect tufts or soft fuzzy patches, to 8 mm high, lavender- red to dark olive- green. Filaments 20-40 urn diam., forming false branching. Trichomes one per sheath, merging with age, tapering from base, ending in a long hair. Cells 9-13 urn diam., swollen base 13-22 urn diam., 10-60 urn long; not constricted at cross walls. Sheaths clear, colorless or yellowish, striated, 8-20 um thick. Heterocytes spherical, cone- shaped to elongated, 20-25 um diam., 20-60 um long, basal or intercalary. Common: generally epiphytic on other marine plants, forming small pads or fuzzy clumps; intertidal to 2 m deep. Highborne Cay Distribution: found intermixed with other species in all Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Smithsonian Institution.
