Within the framework of study on rust fungi (Uredinales) of Khuzestan, 23 rust species belonging to different genera were identified. Of these, 20 species viz., Aecidium rubellum, Melampsora cf pulcherrima, Phakopsora zizyphi-vulgaris, Phragmidium bulbosum, Ph. rosae-lacerantis, Puccinia aeluropodis, Pu. calcitrapae, Pu. cancellata, Pu. conclusa, Pu. malvacearum, Pu. pulvinata, Pu. rhagadioli, Pu. scirpi, Tranzschelia discolor, Uromyces anthyllidis, U. glycyrrhizae, U. gypsophilae, U. lineolatus, U lot/ and U. rumicis are reported as new members for Khuzestan rust flora. Moreover, several new host species are reported for some identified rusts in Iran. Examination of the type and authentic specimens of Puccinia rhagadioli and Pu. garhadioli revealed that both species are identical and, therefore, Pu. garhadioli is considered as a taxonomic synonym of Pu. rhagadioli.
