| CELLULAR |
| Staining | usually stain Gram-positive at least in the very early stages of growth but in some species Gram positive cells have not been seen |
| Morphology | rods |
| Motility | |
| Specialized structures | The oval or spherical endospores usually distend the cell Some species will grow but not sporulate in the presence of air. |
