Contribution to the smut fungi of Greece

Abstract

After examination of specimens in the herbarium of the Botanic Garden and Botanical Museum Berlin, eight species of smut fungi are reported for the first time from Greece: Microbotryum dianthorum on Dianthus viscidus, Sporisorium pulverulentum on Saccharum strictum, Tilletia fusca on Vulpia ciliata, T. lolii on Lolium temulentum, Urocystis dactylidina on Dactylis glomerata subsp. hackelii, U. johansonii on Juncus bufonius, U. ornithogali on Ornithogalum sp. and U. ulei on Festuca jeanpertii. Four species of smut fungi are recorded on new host plants making new fungus-host combinations: Microbotryum dianthorum on Dianthus viscidus, Tranzscheliella williamsii on Stipa isoldeae, Urocystis dactylidina on Dactylis glomerata subsp. hackelii and U. ulei on Festuca jeanpertii. Two plant species are reported as new hosts of smut fungi already known from Greece: Stipa isoldeae for Tranzscheliella williamsii, and Lygeum spartum for T. hypodytes. All ten species of smut fungi are illustrated. A description is also provided for Urocystis agropyri, recorded in Greece on Thinopyrum junceum.
