Pseudostaurosira parasitica is a small, linear to lanceolate freshwater diatom that often grows as an epiphyte on other aquatic organisms. It inhabits benthic and epiphytic habitats in rivers, lakes, and ponds across temperate and boreal regions worldwide. This photosynthetic diatom contributes to attached algal biofilm communities in freshwater systems.
