Thalli rigid and elongated, filamentous, much coiled and contorted when young, later loosened and entangled among other algae, up to 22 cm long. Filaments unbranched, attached to the substratum by a few simple or slightly branched, short and blunt rhizoids. Basal cells inconspicuous, 500-600 µm diameter and 2-3 diameters long and a few cells above the basal one, the filaments coiling spirally. The cells monoliform to nearly cylindrical, 400-630 µm diameter, 0.5-1.5 diameters long.
