Description: | Cladosporium herbarum (Pers.) Link: Fr. Colony characteristics. Colonies (MEA 2%) moderately expanding, velvety, olivaceous green to olivaceous brown; reverse olivaceous black. Microscopy. Conidiophores up to 250 µm long, 3-6 µm wide, with terminal and intercalary swellings and geniculate elongations, pale to mid olivaceous brown or brown, smooth-walled. Conidia ellipsoidal to cylindrical, with rounded ends, distinctly verrucose, with protuberant, brown scars, often 2- or more-celled, when 1-celled measuring 5.5-13.0 x 3.8-6.0 µm. Teleomorph. Davidiella tassiana (de Not.) Johanson (Ascomycota, Euascomycetes, Dothideales: Myco-sphaerellaceae). Pathogenicity. BSL-1. Very common saprobe on decaying plant material, frequently encountered in the clinical laboratory as a culture contaminant. This species was isolated from skin lesions (de Bièvre, 1982) and was reported as a possible agent of keratitis (Pritchard & Muir, 1987). Allergic pulmonary mycosis was reported by MuÀ±oz-Ancillo et al. (1996). References. De Vries (1967), Ellis (1971), Domsch et al. (1980), Prašil & de Hoog (1988), David (1997). Nomenclature.
