Report of some fungi associated with of leaf spot symptoms of self-growing plants in Chaharmahal and Bakhtiari province (Iran)

In order to identify some fungi associated with leaf spot symptoms of some self-growing plants, infected plant samples were collected from fields, gardens and natural habitats in different regions of Chaharmahal and Bakhtiari province of Iran during the spring and summer of 2018. After isolation and purification of fungal strains, morphological and molecular investigations were performed using the nucleotide sequences of one or few genomic regions (depending on the studied fungal genus). Based on combined data, finally, 11 different fungal species belonging to nine different genera including Calophoma complanata, Colletotrichum lini, Didymella pisi, Fusarium acuminatum, F. equiseti, Gnomoniopsis idaeicola, Nothophoma gossypiicola, Petriella sordida, Pyrenophora seminiperida, Sporormiella intermedia,and S. similis are identified and introduced from new host plants. In the present study, among the identified taxa, four species including C. complanata from Falcaria vulgaris, N. gossypiicola from Euphorbia helioscopia, S. intermedia from Mentha pulegium, and S. similis from Euphorbia helioscopia are reported for the first time as new records for mycobiota of Iran.
