Abstract

 
In this study, twenty-one isolates of the genus Colletotrichum with straight conidia were isolated from leaf spots on wild Poaceae plants in three provinces of Iran, including East Azarbaijan, Golestan, and Guilan. Based on morphology, the isolates belonged to three morphotypes. Representative isolates were studied by a polyphasic approach, which included morphology, and phylogeny inferred from multi-locus sequences including the nuc rDNA ITS1-5.8S-ITS2 (ITS), partial sequences of the β-tubulin (TUB2), and actin (ACT) genomic regions. Three distinct species were identified namely C. chrysophilum, C. destructivum and C. orientalis.  Colletotrichum chrysophilum and C. orientalis are new records for the Funga of Iran. This study provides new insights into the host range and geographical distribution of these identified species.
