H. werneckii causes a rare superficial and non-invasive skin infection tinea nigra. [10] The typical symptoms are non-scaly, smooth, brown-black painless spots on the palms of hands and soles of feet. The growth of H. werneckii in liquid media is often yeast-like, although it can switch to filamentous growth. The mechanism of the switch is not ...
