Abstract: Objective Two hundred and eighty seven strains of fungi isolated from the cutaneous lesions in patients with chromoblastomycosis from Zhang Qiu county and its surrounding region were observed and analysed. Methods The fungi were cultured and the morphologic characters of colonies were observed under scanning electron microscope. Results There were 283 strains of C.carrionii, 2 strains of F.pedrosoi, 1 strain of P.verrucosa and 1 strain of undeterminate phialophora sp.were identificated. Conclusion The predominant pathogenic fungi isolated from patients with chromoblastomycosis in Zhang Qiu county and its surrounding region were C.carrionii which confirms that the pathogenic fungi in nothern China is C.carrionii.
