Morphology: Motile cells are ovate to oblong and slightly metabolic with a golden-green parietal plastid. The anterior flagellum is visible and bears hairs and knob scales. A well-developed haptonema emerges adjacent to the anterior flag- ellum, sometimes with fine filipodia. The vestigial posterior flagellum is reduced to the axoneme structure and is covered by small clavate knob scales, like the entire cell body external to the plasma membrane. A pyrenoid and an eyespot were not observed. One or two plastids are present with a parallel helicoidal arrangement of thylakoid lamellae as in E. gayraliae. [Bendif et al. 2011]
