General Notes and Morphology

Aspergillus species are ubiquitous the environment and some are highly resistant to heat and drying. They are saprophytic and frequently live in soil, vegetation, feed and acquire nutrients from dead plant and animal matter. Their spores are produced in large numbers and are spread widely by air currents. In fermented plant matter (e.g. hay, silage, compost) some species (e.g. Aspergillus fumigatus) can dominate over other microorganisms. (B92) (B88)
Reproduction Sexual Spores If sexual reproduction occurs in a species, it will produce ascospores(B88)
Conidia "Aspergilli produce a distinctive conidiophore which consists of a stalk that arises from a specialized cell of the mycelium called a foot cell. The stalk is enlarge at its uppermost point to form a globose, hemispherical, flask-shaped or clavate structure called the vesicle. From fertile areas of the vesicle arise peg-like, conidium-producing cells called sterigmata. The sterigmata may be formed in a single layer or may be arranged in two layers (biseriate) with the second row arising for the first. The sterigmata form unbranching chains of conidia from their distal ends. (B92)"

These fruiting bodies are important diagnostic features. (B88)
