| Morphology | Vegetative cells are straight rods with tapered ends, 0.6-0.8 x 4-10 um. |
| Motility | gliding motility |
| Specialized structures | Myxospores are 0.9-1.2 x 2-4 um, phase-dense or refractile. Sporangioles occur either singly or in clusters on stalks |
| Division |
| COLONIAL |
| Solid surface | Vegetative swarms on agar are yellow-orange to red- brown, do not penetrate or etch agar, and absorb Congo red. |

| Products | |
| Enzymes | Nitrate is not reduced. This organism is catalase-positive, is oxidase-negative, and hydrolyzes starch, Tween 80, indoxyl acetate, RNA, DNA, gelatin, casein and esculin. Urea is usually hydrolyzed (McCurdy 1974). |
