Some of them such as maple tar spot affect health of host trees severely, but many are of minor effect. This study was carried out to identify unknown and less known fungi causing leaf spot and leaf blotch diseases on broad leaf trees in this region. So far numerous fungi were collected. Four species viz. Sphaeropsis mespili (on Mespilus germanica), Seiridium unicorne (on Crataegus melanocarpa), Septoria cornina (on Cornus sanguinea) and Tubakiadryina (on Quercus castaneaefolia) and two unidentified species belonging to Cylindrogloeum sp. (on Fraxinus excelsior) and Monostichella sp. (on Corylus avellana) are recorded for the first time from Iran. Furthermore, Phloeospora aceris (on Acer cappadocicum) andMarssonina juglandis (on Pterocarya fraxinifolia) are new members to Guilan mycobiota. %U https://rostaniha.areeo.ac.ir/article_101432_787d9a188b118c4ddde4c5137394880a.pdf
