Macromorphology (smell):
   | The colonies are initially white, but the colour turns black after a few days when conidia spores begin to form. The colonies grow all over the plate. |
|---|
Micromorphology:
  | The conidial spores are dark brown in color and 4-5 µm in diameter. |

| Metabolism:
|
Aspergillus spp. are aerobic and chemorganotrophic organisms. They are extremely important in degrading organic matter in nature. A. niger is thermotolerant. |

| Reservoir:
| Can be found everywhere in soil. |

| Disease/effect:
| Aspergillosis is usually caused by A. fumigatus, but in rare cases A. niger, A.flavus, A. nidulans and A. terreus etc., may also be the causative agent.
