Five smut fungi viz. Microbotryum scorzonerae on Scorzonera caliculata, Sporisorium aristidae-lanuginosae on Stipagrostisplumosa, Sporisorium desertorum on Lasiurus sindicus, Sporisorium foveolati on Dichanthium foveolatum,and Sporisorium vanderystii on Hyparrhenia hirta are reported for the first time for Iranian mycobiota. Sporisorium foveolati is also probably new to Asia. Bellevalia saviczii is also reported as a new host for Antherospora tourneouxii. The latter species was previously known from Iran as Vankya vaillantii on Bellevalia glauca. All recorded species are redescribed and illustrated by microphotographs.
