| CELLULAR |
| Staining | Gram-variable. Young cells tend to be Gram- negative; older cells are mainly Gram-positive. Cell sections examined with an electron microscope reveal a Gram- positive type of cell wall. |
| Morphology | Very short, sparse aerial mycelium composed of hyphae 0.5- 1.0 um in diameter that grow on the surface of solid media. The aerial hyphae are maintained upright at the surface of the medium by holdfasts, which are outgrowths of the wall of the basal cell. Primary (substrate) mycelium not formed. The sparingly branched aerial mycelium divides into rod- shaped to coccoid spores, which, in the presence of water, may become polarly flagellate and motile. |
| Motility | On nitrogen-rich media the spores swell to give rise to swollen elements of various shapes, including fish-shaped structures, which may be motile |

| Unique features | . Cell wall preparations contain major amounts of L-diaminopimelic acid (L-DAP), glycine, alanine, glutamic acid, glucosamine, and muramic acid. Because of the difficulties of obtaining enough cells for analysis, there are no data on phospholipid, menaquinone, or DNA composition.. |
