Abstract:
We report a case of onychomycosis due to Fusarium solani with gray-green staining, which improved after nail plate removal and antifungal liquid of effinaconazole. Fungal cultures revealed light-brown and dark-green colonies. Gray-green nail might have occurred due to the combination of these colonies, which necessitated differentiation from green nail. Fusarium solani was detected on the genetic analysis of the colonies. Fusarium species reportedly produce yellow or red pigments; however, Fusarium species has not been previously reported to produce green pigments or forming dark-green colonies in fungal cultures.

Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
