Abstract
During 2006-07, extensive leaf spot symptoms were observed on elm trees
(Ulmus minor Mill.) existed on river sides around Hamedan. In order to isolate the pathogenic agent, several pieces of infected leaves were plated on PDA (potato-dextrose agar, Merck) and MEA (malt extract agar, Merck) after surface disinfection with 0.5-1% sodium hypochlorite Microscopic slides of the hand-sectioned specimen were prepared in cotton-blue and water and studied subsequently. According to literatures review (5, 6) the teleomorphic fungus was identified as Platychora ulmi (Schleich.: Fr.) Petr., with the anamorphic stage known as Piggotia ulmi (Grev.) Keissl.
