| CELLULAR |
| Staining | |
| Morphology | Cells are spherical and small, 0.2-0.5 um in diameter and occur singly or in small aggregates which may sometimes resemble an ear of corn (Zea mays) and sometimes are just irregular |
| Motility | Zavarzin (1974) claimed cells were motile, but the type of flagellation is unknown. Other authors do not mention motility |
| Specialized structures | .. Cells were originally described as carrying filamentous appendages (Dorff 1934; Kutuzova 1974). The latter author observed very fine branching filaments, especially when the cells were kept under reducing conditions. Dorff (1934) was unable to find capsules, but Kutuzova (1974) stresses that electron microscopic studies definitely showed capsules to be present and that the iron oxides were precipitated into (onto) these. Multiplication is by budding; the cells may then become slightly pear shaped. Often, young buds occur again, thus giving rise to budding cell chains or even nets (Kutuzova 1974; P. Hirsch, unpublished observations). The organisms usually develop as largeaccretions. Iron oxidation and deposition around the cells may be considerable; the deposits are bright yellowish orange |

| Habitat | "Siderococcus" microzones are especially common in mud horizons with low concentrations of oxygen and at neutral pH (Perfil'ev and Gave 1964), such as in groundwater iron springs in which the cold water oozes out horizontally, and are widely distributed in freshwater bottom deposits |
