New records of Colletotrichum species for the mycobiota of Iran

Sixteen isolates of Colletotrichum were collected from leaves with anthracnose symptoms or leaf spots of twelve wild, cultivated and ornamental plant species from the Guilan, Mazandaran, and Golestan provinces in Northern Iran. Five different species, including C. aenigma, C. gigasporum, C. godetiae, C. karstii, and C. musae were identified based on the DNA sequence data (TUB2, GS, GAPDH). Four of these species, termed as C. aenigma, C. gigasporum, C. godetiae and C. karstii represent new records for the mycobiota of Iran. Moreover, this study reports many plants as new hosts of Colletotrichum species. Comprehensive morphological descriptions and illustrations are provided for the species.
