Pinnularia divergentissima is a large, boat-shaped freshwater diatom with strongly diverging costae radiating from the central area to the valve margin. It inhabits acidic, oligotrophic freshwater environments including mountain streams, peat bogs, and soft-water lakes. This photosynthetic diatom is a bioindicator of acidic, nutrient-poor freshwater conditions.
