A yeast that reproduces by the formation of arthrospores. Colonies are white and yeast-like but later produce white cottony aerial mycelium. It has worldwide distribution and is very common because it is part of the normal fungal flora of humans and animals. It can be isolated from contaminated grains, fruits, dairy products, paper, textiles, soil, and water. It can be an opportunistic human pathogen causing skin, pulmonary, mouth, and intestinal infections, especially in immunocompromised patients.
