As a mycologist with extensive experience in the study of fungi, I am well-versed in the characteristics of various species within the Aspergillus genus. The color of Aspergillus is a distinctive feature that helps in the identification of different species. It is important to note that the Aspergillus genus is diverse, and the color can vary significantly from one species to another.
Aspergillus fumigatus, which is the most common species to infect humans, is known for its greenish color. However, the color of Aspergillus is not limited to this one species.
Aspergillus flavus, as mentioned, is characterized by a yellow-green surface color and can appear gold or red-brown underneath. This species is particularly known for its ability to produce potent mycotoxins, such as aflatoxins, which can contaminate crops and pose a significant health risk to humans and animals.
The coloration of Aspergillus species is influenced by various factors, including the presence of conidia, or spores, which are often the most visible part of the fungus. The conidia can be of different colors, ranging from green, yellow, brown, to black, depending on the species. For instance, Aspergillus niger is known for its black coloration, while Aspergillus oryzae is typically associated with a yellowish hue.
In a laboratory setting, the identification of Aspergillus species is often done through microscopic examination of the conidia and the structure of the mycelium, as well as through biochemical and molecular tests. The macroscopic appearance, including color, is a preliminary step in the identification process but should be corroborated with other methods for accurate species determination.
It is also worth mentioning that the color of Aspergillus can be influenced by environmental conditions, such as the substrate on which it is growing, temperature, and humidity. These factors can affect the pigmentation and growth patterns of the fungus, sometimes leading to variations in color even within the same species.
In summary, the color of Aspergillus is a key characteristic for species identification but should be considered alongside other morphological and genetic markers. The genus encompasses a wide range of colors, from the green of Aspergillus fumigatus to the yellow-green and red-brown of Aspergillus flavus, and the black of Aspergillus niger, among others. Understanding these color variations is crucial for accurate diagnosis and treatment of fungal infections, as well as for food safety and agricultural practices.

After Aspergillus fumigatus, Aspergillus flavus is the second most common Aspergillus mold to infect humans. The surface of Aspergillus flavus is yellow-green in color and it is gold or red brown underneath.
