描述：

Colonial chrysophyte flagellate, Dinobryon sertularia (EHRENBERG,1834) . Cells in vase shaped loricae. During division, daughter cells in this species attach to the inner surface of the mother cell lorica, giving rise to typical branching colonies. Loricae are composed of cellulosic microfibrils. Cells with two unequal flagella. Two large chloroplasts. Prominent stigma. Mixotrophic because the cells can phagocytose bacteria as well as carry out photosynthesis. From freshwater pond near Boise, Idaho. Oblique illumination.
