Results of gross and microscopic morphology and microbiological laboratory testing to identify Trichophyton indotineae in a woman in Pennsylvania, USA. A, B) Colonies were velvety white, flat, and had a raised center (arrow) (A) and a light yellow pigment on reverse (B). C) Numerous microconidia showed the pyriform and clavate forms (black arrow) and fungal hyphae with septation (blue arrows). Original magnification ×40. D) In vitro hair perforation test was positive (arrow). Original magnification ×100. E) T. indotineae had a negative urease test (yellowish color), while the positive control, Trichophyton tonsurans, was pinkish.
