Due to the variety of vegetation and high humidity, the Northern provinces of Iran are the habitat of many medicinal mushrooms. Genetic variation of medicinal mushrooms in Iran is poorly studied. 30 isolates of Trametes versicolor were collected from different localities in Guilan, Golestan, and Mazandaran provinces (North of Iran). The genetic diversity was evaluated by ISSR marker. 86 bands were observed using eight polymorphic primers. Cluster analysis showed that the isolates divided into 18 groups at a level of 0.22 similarity coefficient. SI indices were 0.335, 0.305 and 0.217 in Guilan, Golestan, and Mazandaran populations respectively. 96% genetic variation was observed within populations. The diverse geographic origin of the isolates is an influential factor in the high intra-population genetic diversity of the fungus.
