Every dermatology laboratory in teaching hospitals is faced with the problem of maintaining an adequate teaching collection of fungal specimens. Even under optimal conditions some species gradually lose their characteristic morphology and undergo pleomorphic degeneration. The advantages of using dried fungal cultures as teaching aids are therefore brought to the attention of dermatologists. Cold plastic embedding of dried cultures yields permanent preparations which are stable, practically unbreakable, and easily stored.
