Abstract The manganese-accumulating microorganism Metallogenium is very common in the deep water and on the sediment surface in lakes of the Oslo district, southern Norway. Metallogenium accumulates manganese in its star-shaped coenobia; other trace metals are also greatly concentrated. The taxonomic position of the organism is uncertain. Sections of coenobia suggests that the encrusted parts are not enclosing living structures. In lake Nordbytjern, the occurrence of Metallogenium coincides with periods of turbulence in the lake. By sinking, the population accumulates close to the chemocline, becoming heavily encrusted. Plankton traps indicate that Metallogenium adds to the downward transport and accumulation of manganese and iron in the lake.
