Tinea versicolor scales, prepared by the method about to be detailed, have remained in excellent condition for seven months (fig. 1), as have skin scrapings containing Trichophyton hyphae (fig. 2). The general procedure will be described first, followed by suggested modifications for different categories of clinical specimens. A.
