Fungal diseases are called mycoses and those affecting humans can be divided into four groups based on the level of penetration into the body tissues. (view-How Common are Fungal Diseases). 1  Superficial mycoses are caused by fungi that grow on the surface of the skin or hair.2  Cutaneous mycoses or dermatomycoses include such infections as athlete's foot and ringworm, where growth occurs only in the superficial layers of skin, nails, or hair.Subcutaneous mycoses penetrate below the skin to involve the subcutaneous, connective, and bone tissue.utaneous mycoses or dermatomycoses include such infections as athlete's foot and ringworm, where growth occurs only in the superficial layers of skin, nails, or hair.
