TheOnygenalesare anorderof fungi in the classEurotiomycetesand divisionAscomycota.The order's last common ancestor is estimated to have lived 150 million years ago.[1]
Onygenales can consume and break downkeratin,the main component of the outer layer of skin.[2]They are primarily found on animals, droppings, and areas frequented by animals. Many aredimorphic,and can change from mold to yeast form depending on their environment.[1]
Many onygenalean fungi arepathogens.[1]One species,Trichophyton rubrum,is the primary cause ofathlete's foot.This order also includes theCoccidioidesimplicated inValley fever.The Onygenales are important as emerging human pathogens because of the rising rates ofimmunosuppressiondue to live-organ transplant, HIV/AIDS, andautoimmunedisorders such aslupus erythematosus.[3][page needed]
