have sheaths are a lso included in Nonphotosynthetic,
Nonfruiting Gliding Bacteria in
the non fruiting section. The genus Lyngbya which is one of the cyanobacteria also has
a sheath. Clonothrix fusca Crenothrix polyspora, Haliscomenobacter hydrossis, Leptothrix, Lieskeella bifida Phragmidiothrix multiseptata Sphaerotilus natans , Thioploca, Thiothrix nivea, Herpetosiphon |

| CELLULAR |
| Staining | |
| Morphology | Cells of variable size, usually small and disk-shaped, with a diameter 4-6 times the thickness of the cell. Cells are arranged as colourless, articulate and unbranched filaments of over 100 um in length. |
| Motility | |
| Specialized structures | Filaments attached, forming grayish-white tufts. The free end may be of larger diameter than the base, but there is no tapering in either direction; the diameter varies between 3 and 6 um. Surrounded by a very thin, delicate, gelatinous, colourless sheath which is not encrusted with iron or manganese compounds. Cell walls are distinctive and of even thickness throughout the filament. Multiplication is by cross-septation and, in certain regions of the filament, by both cross-septation and longitudinal septation, forming Sarcina-like aggregates of small, nearly cubical propagation cells. Septating cells may be of greaterdiameter, causing localized swelling of the filament; in areas septating in both planes, the filaments may be up to 6 um indiameter. |
