Aspergillus (/ ˌ æ s p ər ˈ dʒ ɪ l ə s /) is a genus consisting of several hundred mold species found in various climates worldwide. Aspergillus was first catalogued in 1729 by the Italian priest and biologist Pier Antonio Micheli .
The hyphae of Aspergillus species range in diameter from 2.5 to 4.5 μm. They have septate hyphae, [28] but these are not always apparent, and in such cases they may be mistaken for Zygomycota. [27] Aspergillus hyphae tend to have dichotomous branching that is progressive and primarily at acute angles of around 45°. [27]
Aspergillus ochraceus is a mold species in the genus Aspergillus known to produce the toxin ochratoxin A, one of the most abundant food-contaminating mycotoxins, and citrinin. It also produces the dihydroisocoumarin mellein .

Aspergillus penicillioides is a species of fungus in the genus Aspergillus, and is among the most xerophilic fungi. [1]Aspergillus penicillioides is typically found in indoor air, house dust, and on substrates with low water activity, such as dried food, papers affected by foxing, and inorganic objects such as binocular lenses. [2]
Aspergillus terreus, also known as Aspergillus terrestris, is a fungus (mold) found worldwide in soil. Although thought to be strictly asexual until recently, A. terreus is now known to be capable of sexual reproduction. [ 2 ]
