Description

Ulothrix aequalis consists of uniseriate filaments of cells. The cells are cylindrical, 12–22 microns broad and 26–30 microns long. They are attached a cell or rhizoids at the base.Guiry, M.D., John, D.M. Rindi, F. and McCathy, T.K. (Ed) 2007.

Cells each contain a broad, girdle-shaped chloroplast which covers at least half of the cell circumference; the chloroplast has one or two pyrenoids.

Asexual reproduction is by zoospores or aplanospores. Akinetes are also produced, and they lack distinct ornamentation. Sexual reproduction is via biflagellate gametes.
