Aptly named for its “versicoloured” colonies, which can range from pinkish to yellow, green, or even brown. A. versicolor is frequently isolated in damp indoor environments, such as water-damaged walls or ceiling tiles. It has been associated with the production of sterigmatocystin, a mycotoxin structurally related to aflatoxins, posing potential health risks. Prolonged exposure to large spore concentrations can irritate the respiratory tract and aggravate asthma or allergies.
