Identification of some grass-associated species of Bipolaris, Curvularia and Exserohilum in selected regions of Iran

Infected tissues of roots and leaves of various grasses as well as soil around their rhizosphere were sampled from Fars, Golestan, Isfahan, Khorasan Shomali, Khorasan Razavi, Mazandaran and Semnan provinces (Iran). Based on morphological characteristics and available keys, four species of Bipolaris including B. austreliensis, B. indica, B. micropus and B. spicifera, four species of Curvularia including C. akaiiensis, C. heteropogonicola, C. protuberata and C. verruculosa and two species of Exserhilum including E. gedarefense and E. pedicellatum were identified. Bipolaris austreliensis and B. spicifera widely distributed in Iran. Bipolaris micropus, C. protuberata, C. akaiiensis, E. pedicellatum and E. gedarefense are new to Iran mycobiota.
