Report of some fungi of Pleosporaceae family associated with leaf spot symptoms of plants in Chaharmahal and Bakhtiari province, Iran

In this study, 32 plant samples with leaf spot symptoms were collected from chaharmahal and bakhtiari province, iran, in the spring and summer of 2018. isolation and purification of 26 fungal isolates were performed on 2% water agar and potato dextrose agar to identify the causal agents. fungal species were identified according to morphological characteristics and molecular data obtained from glyceraldehyde 3-phosphate dehydrogenase (gpdh) gene sequences. in this research, 11 species belonging to four genera of hyphomycetous fungi, including alternaria cantlous, a. consortialis, a. multiformis, bipolaris sorokiniana, b. zeicola, curvularia spicifera, c. nicotiae, c. inaequalis, stemphylium beticola, s. symphyti, and s. vesicarium are introduced. among them, three species, including c. nicotiae from salvia officinalis l., s. beticola from plantago major l., and s. symphyti from mentha pulegium l., are reported as new records for mycobiota of iran. all collected plant species are reported as new hosts (matrix nova) for the identified fungal taxa.
