The microscopic examination of lesions of patients with suspected mycotic infections using slides purchased from foreign countries often showed hyphae. The slides and their wrappings were cultured successfully on Sabouraud dextrose-agar medium. A heavy growth of suspected aspergillus colonies was obtained. These colonies were investigated further by culturing them on both Czapek's solution agar and Malt extract agar. After macroscopic and microscopic examination the fungus was identified as Aspergillus chevalieri from the Aspergillus glaucus group. (7 Clin Pathol 1997;50:699-700) Keywords: Aspergillus glaucus; contamination; microscope slides; mycotic infection Aspergillus species are common airborne contaminants of all surfaces, including skin, mouth, lung, wounds, and so forth. There are about 900 species in the genus Aspergillus. They are among the most common of all environmental fungi. Members of the aspergillus genus are often identified as biodeteriogens. The large number of species comprising the
