 Later, the fungal parasite was called "Achorion schoenleinii" in Schönlein's honor.In 1842 he described a microscopic cryptogam ("Trichophyton ectothrix") that is associated with a dermatological disease known as "sycosis barbae".Gruby also discovered "Candida (Monilia) albicans", the cause of candidiasis, and in 1843 he described a fungus ("Microsporum audouinii") that is the cause of a type of ringworm.
