ABSTRACT: This article lists one new Puccinia species and six otherwise noteworthy Iranian rust fungi (Uredinales) on Poaceae. New to science is Puccinia ariorum sp. nov., a species with verrucose teliospores on Bromus danthoniae. Puccinia australis on Cleistogenes serotina, P. fragosoana on Imperata cylindrica, Uromyces ferganensis on Stipa caucasica and S. holosericea, and U. setariae-italicae on Panicum sp. and Setaria glauca are reported for the first time for Iran. Puccinia stipae var. stipina was found for the first time on a telial host (S. pennata subsp. zalesskii and S. holosericea) in Iran, Finally, a very rare species, P. schoenanthi, was found on Cymbopogon olivieri in southern Iran. All specimens are described in detail and some are documented with microphotographs.
