Conidial heads of Aspergillus terreus are compact, columnar and biseriate; conidiophores are hyaline and smooth-walled; and conidia are globose to ellipsoidal, hyaline to slightly yellow and smooth-walled.

Ecology Aspergillus terreus is a cosmopolitan fungus which is primarily isolated from compost, plant material, and from soil. Aspergillus terreus is more common in tropical or sub – tropical areas. Pathogenicity and Health Effects Aspergillus terreus is an occasional causative agent of pulmonary aspergillosis among immunocompromised patients. A few cases of cerebral infection have been reported. Aspergillus terreus is isolated occasionally from outer ear canal colonizations. Macroscopic Appearance
Ø Growth rate is rapid and texture of colonies varies from downy to powdery; and Ø Surface colony color is beige to buff to cinnamon while reverse is pale yellow to brown with yellow soluble pigments that are frequently present.
Microscopic Appearance
Ø Hyphae are septate and hyaline and conidial heads are in the form of compact columnar and contains metulae which supports the phialides, also called as biseriate; Ø Conidiophores are smooth – walled, with length ranging from 70 - 300 µm long, and terminating in mostly globose vesicles; Ø Conidia are globose, smooth, and small with size of 2 – 2.5 µm in diameter; and Ø Accessory conidia are hyaline, globose, sessile, with size of 2 – 6 µm, and are frequently produced on submerged hyphae.
