Microsporum canis is a fungus that can cause tinea capitis in humans, and simple ringworm in pets.[3] The organism's major reservoir in companion animals is within domestic cats and dogs. Under Wood's lamp examination, it gives bright green fluorescence 30–80% of the time.[4]

It is closely related to other dermatophytes.[5]
