- Also can never be classified in   

Animalia Because can not move.

        Where these fungi form colonies in keratin tissue and then Inflammation as a reaction of the body on the secondary metabolic products of fungi happen.       

       In general, there is this fungus  on the horny layer of the skin.

Because of its inability to penetrate the living tissue of the host immune body is healthy.

        Each of the following enzymes: Brotenase, Aalastase, Kiratnase, and other enzymes degrading proteins also play a role in virulence this fungus.
Usually called a fungal skin infection that cause ringworm name or, Tinea.

 

Tinea of Types  :

1 Tinea pedis           (foot)

2 Tinea unguium      (nails)

3 Tinea manuum     (hand)

4 Tinea cruris           (groin)

5 Tinea corporis       (body)

6 Tinea capitis         (scalp)

7 Tinea faciei           (face)

8 Tinea barbae        (beard)

9 Tinea imbricata    (overlapping pattern)

10 Tinea nigra         (black)

11 Tinea versicolor  (various colors)

Tinea pedis : (foot)

      Athlete's foot (also known as "ringworm of the foot",[2] tinea pedum,[3] and "moccasin foot"[4]) is a common and contagious skin disease that causes itching, scaling, flaking, and sometimes blistering of the affected areas. Its medical name is tinea pedis, a member of the group of diseases or conditions known as tinea, most of which are dermatophytoses (fungal infections of the skin), which in turn are mycoses (broad category of fungal infections). Globally, athlete's foot affects about 15% of the population.[4]

Tinea pedis is caused by fungi such as https://en.wikipedia.org/wik
