What colors may the balls in A. Flavus appear?

  1. Only white

  2. Blue and purple

  3. Yellow, green, olive, or brown

  4. Red or orange

The correct answer is: Yellow, green, olive, or brown

The presence of colors such as yellow, green, olive, or brown in A. flavus balls is a characteristic feature of this species. A. flavus is known for producing conidia that can manifest these various hues, which is important for identification and understanding its biology. These colors result from the pigmentation of the spores and can vary between cultures and environmental conditions. Understanding these color variations aids peanut inspectors in quickly identifying potential contamination during inspections. The other color options reflect hues associated with either different fungi or specific growth conditions that don’t align with the recognized characteristics of A. flavus. Knowing these details is crucial for effective detection and compliance in industry practices regarding peanut safety and quality.
