A much-needed rapid contrast stain for fungi to be used as an aid in diagnosis is described. It may be used for the examination of infected skin scales, nail scrapings, hair samples, sputa, and pus caused by the dermatophytes, Candida albicans, Geotrichum, Aspergillus species, and doubtlessly other fungi. This stain is also useful for studying culture mounts.
