How would you describe Aspergillus?
Aspergillus is defined as a group of conidial fungi—that is, fungi in an asexual state. Some of them, however, are known to have a teleomorph (sexual state) in the Ascomycota. With DNA evidence, all members of the genus Aspergillus are members of the phylum Ascomycota.
What does Aspergillus flavus look like under the microscope?
The microscopic characteristics of Aspergillus flavus isolate 5 under the basic biological light microscope showing the biseriate with philiades radiating from all sides (a); the globose conidia with varying sizes that are slightly roughened (b); and unbranched conidiophore which is nonseptate, rough, and hyaline (c).
How do you identify Aspergillus mold?

What is the appearance of Aspergillus?
Surface: Initially white and then any shade of yellow, green, brown, or black, depending on species. Texture is velvety or cottony.
What is the structure of Aspergillus?
In Aspergillus, the predominant cell wall components are polysaccharides synthesized by transmembrane synthases, transglycosidases and glycosyl hydrolases. The main core of A. fumigatus cell wall consists of a polymer of β-1,3-glucan and chitin which is responsible for the rigidity of this structure.
