This study aimed to isolate and identify dematiaceous fungi from soil of Mashhad, Neyshabur and Isfahan cities. Of 93 strains isolated, the frequency of Ulocladium, Cladosporium, Aureobasidium and Alternaria were as 38.7%, 30.2%, 10.7% and 6.4%, respectively by microscopic examination. Also 13.9% were sterile hyphae. In this study, ulocladiumsp were the predominant fungi among all of the dematiaceous fungi. Although ulocladiumsp that formerly was identified as non-pathogenic saprophyte, have recently been reported in various diseases such as asthma, allergic rhinitis, hypersensitivity pneumonitis, chronic wounds, onychomycosis, cutaneous granulomas and keratitis.
