Psammothidium acidoclinatum is a small, benthic freshwater diatom found attached to acidic substrates in oligotrophic lakes, bogs, and soft-water streams. Its siliceous cell wall is distinctly asymmetric, with valves shaped to facilitate attachment to sediment grains. This species is a useful bioindicator of water chemistry, particularly acidity, in freshwater ecology studies.
