Emericella quadrilineata belongs to the Emericella group. Emericella is a fungus, an ascomycete that multiplies by sexual reproduction with genetic exchange. The Emericella species are known as the sexual states of the Aspergillus species, particularly Aspergillus nidulans. This fungi species is also closely related to the Eurotium group, which also has Aspergillus anamorphs.

Emericella quadrilineata is commonly found in tropical and subtropical climates. Outdoors, it is isolated from plants, plant material and soil. Indoors, it can be isolated from the likes of building materials and even house dust. It can also be found in food products, as the Emericella species usually cause food spoilage.

Like all others that belong to the Emericella group, Emericella quadrilineata grows in a rapid rate. Its colony color can differ: it can be gray, green, purple or yellow. The colony also usually has a velvety texture. This fungus is allergenic and may cause asthmatic reactions.
