Subcutaneous mycoses—fungal infections beneath the skin, usually caused by spores or mycelial fragments of soil organisms that enter through a puncture wound. Sporotrichosis is an example. 3. Dermatomycoses or cutaneous mycoses—these infect only the epidermis, hair, and nails. The fungus organisms can be called dermatophytes.
