Phragmidiothrix has a noded, unbranched, colorless mycelium. The mycelium is over 100 microns in length. They attach and form gray-white clumps. The free end can be larger in diameter than the base, but is not sharp in either direction and varies between 3 and 6 microns in diameter. A very thin, delicate, gelatinous colorless sheath surrounds the free end. This sheath is not inlaid with iron or manganese containing compounds. The cells of Phragmidiothrix vary in size, generally small and disc-shaped, with cell diameters 4-6 times the thickness. The cell wall of the bacteria is distinct and the thickness is uniform throughout the mycelium. Phragmidiothrix reproduces by forming a diaphragm, both transverse and longitudinal in certain areas of the mycelium, resulting in small. This in turn produces small, sarcoid-like aggregates resembling three-dimensional propagating cells. The cells that form the septum may have larger diameters, causing local enlargement of the mycelium. The diameter of the partition formed between the two planes can reach 6 microns. Pure cultures have not been performed on artificial media. Originally found attached to the surface of live Gammarus locusta, it was collected from an anaerobic, H2S-containing contaminated area called "Weisser Grund" or "Todten Grund" in the Bay of Kieler, Germany. The bacterium is not uncommon and has been reported on algae in polluted water in the North Adriatic Sea.
