brownish in colour and gets darker as it ages on culture media.On Czapek or malt extract agar (MEA) medium at 25 °C (77 °F), colonies have the conditions to grow rapidly and have smooth-like walls. In some cases, they are able to become floccose, achieving hair-like soft tufts.Colonies on malt extract agar grow faster and sporulate more densely than on many other media.
#Aspergillus_terreus has conidial heads that are compact, biseriate, and densely columnar, reaching 500 × 30–50 μm in diameter. Conidiophores of A. terreus are smooth and hyaline up to 100–250 × 4–6 μm in diameter. The conidia of A. terreus are small, about 2 μm in diameter, globose-shaped, smooth-walled, and can vary from light yellow to hyaline.Unique to this species is the production of aleurioconidia, asexual spores produced directly on the hyphae that are larger than the phialoconidia (e.g. 6–7 μm in diameter).This structure might be influential in the way A. terreus presents itself clinically as it can induce elevated inflammatory responses.
This fungus is readily distinguished from the other species of Aspergillus by its cinnamon-brown colony colouration and its production of aleurioconidia. A. terreus is a thermotolerant species since it has optimal growth in temperatures between 35–40 °C (95–104 °F), and maximum growth within 45–48 °C (113–118 °F).#Clinical_Biologist
