| Morphology | Thermoactinomyces |
| CELLULAR |
| Staining | Gram-positive, not acid fast |
| Morphology | Substrate mycelium well-developed, branched, septate, 0.4- 0.8 um in diameter. Aerial mycelium 0.5-1.0 um diameter, variable in amount, sometimes transient lysing to leave layer of spores. Spores formed singly on aerial and substrate hyphae, sessile or on simple or branched sporophores, globose, often ridged, 0.5-1.5 um in diameter, with the structure and properties of bacterial endospores. |
