Portrait (lateral view) of the chaetophoralean alga, Aphanochaete repens (Braun, 1849). A. repens is epiphytic on filamentous algae (in this case Oedegonium). The cells are cylindrical to cuboid, some bearing one long clear seta with a bulbous base. The cells arrange themselves in files with short branches along the long axis of their host algal filament. Collected from a freshwater pond near Boise, Idaho June 2004. DIC optics.
