Athlete's foot is most commonly caused by the molds known as Trichophyton rubrum and T. mentagrophytes, [22] but may also be caused by Epidermophyton floccosum. [23] [24] Most cases of athlete's foot in the general population are caused by T. rubrum; however, the majority of athlete's foot cases in athletes are caused by T. mentagrophytes. [13]

[2] Traditionally, these anamorphic (asexual or imperfect fungi) mold genera are: Microsporum, Epidermophyton ...
Tinea pedis is caused by fungi such as Epidermophyton floccosum or fungi of the genus Trichophyton including T. rubrum [5] and T. mentagrophytes. [6] These fungi are typically transmitted in moist communal areas where people go barefoot, such as around swimming pools or in showers, and require a warm moist environment like the inside of a shoe ...
Superficial scrapes of skin examined underneath a microscope may reveal the presence of a fungus.This is done by utilizing a diagnostic method called KOH test, [6] wherein the skin scrapings are placed on a slide and immersed on a dropful of potassium hydroxide solution to dissolve the keratin on the skin scrappings thus leaving fungal elements such as hyphae, septate or yeast cells viewable.
The hair perforation test, also known as an in vitro hair perforation test, is a laboratory test used to help distinguish the isolates of dermatophytes, such as Trichophyton mentagrophytes and its variants. [1]
