Abstract: Aspergillus flavus has a world-wide distribution and normally occurs as a saprophyte in soil and on many kinds of decaying organic matter. It is a large genus composed of more than 180 accepted species. The genus is divided in seven sub genera and further divided into sections. As with fungi in general, Aspergillus flavus’s taxonomy is complex and ever evolving (Chang et al., 1995). This particular genus can be identified by its characteristic conidiophores, but species identification and differentiation is rather complex because it is based on the range of morphological features. Some of the morphological features include conidial and mycelial colour, colony diameter, colony reverse colour, production of exudates and soluble pigments, presence of sclerotia and cleistothecia. Its shape and size of vesicle, conidia and conidiospores are considered in micromorpology of aspergillus flavus. A. flavus is known as a velvety, yellow to green or brown mould with a goldish to red-brown reverse, basically yellowish to green color. The conidiophores are variable in length, rough, pitted and spiny. They may be either uniseriate or biseriate. They cover the entire vesicle, and phialides point out in all directions.
