Infected hairs show little or no fluorescence when examined under the Wood’s light. Additionally, a great variety of animals is infected or may serve as a vector of the fungus.
Macroscopic Appearance
Ø Growth rate is rapid and the texture of the colonies ranges from powdery to granular; and Ø The surface colony color is beige to cinnamon brown and the reverse is yellow to brownish red.
