Plants forming tufts. Basal system formed of long branched rhizoidal filaments, spreading on the surface of the substratum. Cells of the rhizoids poor in contents, 49-264 µ long and 15-50 µ broad. Frequently rhizoids arise from the cells of the upper portion of a main filament. Main filament unbranched in the lower portion, becoming profusely branched near about the mid-region. Branching at first monopodial, later irregular. Branches broader at the base, becoming narrower upwards and terminating into long hairs. Cells of the filaments 33-100 µ long and 20-80 µ broad; each cell with discoid chromatophores. Intercalary meristem lying in the middle of the main axis and at the base of the laterals.

Plants bearing plurilocular structures, sporangia or gametangia. Sporangia or gamentangia oblong or oblong-conical, rounded at the bases; 80-130 µ long and 25-65 µ broad; sessile as a rule; placed in a characteristic manner; single or in short rows on the upper side of the branches near the base and especially in the corners. Two, three and sometimes more sporangia or gametangia occurring serially together.

Epiphytic on old leaves of the seagrass, Enhalus acoroides, attached by the decumbent filaments.
