In this study , samples of oily nuts using for human consumption ( pistachio- peanuts- walnut …..) were randomly obtained from markets in three geografical regions (south, east and west) of Tehran. They were immidiatedly sent to Mycology lab. Then they were prepared for detection of fungi on Sabour glucose , Rose bangal and Chapex agars. Analysis of fungi were done by slide-culture, detection of Morphology and culturing on special agar for each fungi. Aspergillus , Penicillium , Fusarium , Mucor, Peicilium and Yeast were separated from samples. Aspergillus (32.2%) and Penicillium (30.3%) in order were the most separated fungi from different samples while yeast was the least(5.6%). The maximum extracted fungi were observed in the Peanuts(26 samples)and Pistachio(30 samples). Regarding the crucial existence of toxin producer fungi ( Penicillium , Fusarium and Aspergillus ) in the studied samples , Controlling toxogenic fungi contamination in these products is very important.
