| Morphology | Dactylosporangium |
| CELLULAR |
| Staining | Gram-positive and not acid fast. |
| Morphology | Finger-shaped to claviform sporangia (0.6-1.4 x 2.5-6.0 um) are formed on short sporangiophores on the substrate mycelium. They are developed singly or in clusters above the surface of the substrate. Each sporangium contains a single row of normally three to four spores. The spores are oblong, ellipsoidal, ovoid, or slightly pyriform (0.4-1.3 x 0.5-1.8 um) True aerial mycelium is not formed. Hyphae of the substrate mycelium are 0.5-1.0 um in diameter, branched, and rarely septate. Large globose spores (1.7-2.8 um in diameter) are formed on short branches on substrate mycelium. |
| Motility | spores are motile by means of a polarly inserted tuft of flagella. |

| Division |
| COLONIAL |
| Solid surface | Colonies grow on various agar media. They are compact, somewhat tough and leathery, and mostly flat or sometimes elevated with a smooth to slightly wrinkled surface. The colour of the substrate mycelium is pale orange to deep orange, rose or wine-coloured to brown. |
