Okellya curvata (Printz) Leliaert & Rueness (earlier Uronema curvatum Printz) grows in the sublittoral and has been found as an epiphyte on red algae. It consists of uniseriate and unbranched slightly curved filaments which are 3-8 cells long, up to 200 um long. Intercalary cells are cylindrical and 3-20 um in diameter, normally containing 2-4 nuclei. The chloroplast is parietal and lacks pyrenoids. Spores develop in the apical and subapical cells, and are released through a single pore in the upper part of the zoosporangium.
