Myriodontium keratinophilum

Apinisia keratinophila, formerly Myriodontium keratinophilum, is a fungus widespread in nature, most abundantly found in keratin-rich environments such as feathers, nails and hair. Despite its ability to colonize keratinous surfaces of human body, the species has been known to be non-pathogenic in man and is phylogentically distant to other human pathogenic species, such as anthropophilic dermatophytes (e.g., Trichophyton rubrum, Trichophyton interdigitale). However, its occasional isolation from clinical specimens along with its keratinolytic properties suggest the possibility it may contribute to disease....read more on Wikipedia.
