Trichosporia in the USSR is rare (in the republics of Central Asia). Infection occurs when using a comb or a headdress of a patient.
On the hair of the head, on the beard and mustache, fungi form hard (like a stone) small nodules, which are visible only under the magnifying glass and are determined by touch, their color from yellowish to black. In the absence of therapy, the disease continues indefinitely.
