Trichoderma viride

T. viride and T. koningii are cosmopolitan species and have been isolated from almost every environment. Soils, composts and vegetables are common sources of these fungi, and cool and moist environments are preferred. T. viride can grow on linoleum and wallpaper, and is probably more commonly isolated from indoor environments in winter months. As a genus, Trichoderma can cause nosocomial (hospital acquired) mycoses from contaminated solutions. T. viride is allergenic and has caused keratitis, peritonitis, pulmonary infections and hematomas.
