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. Citation: Denchev T. T. & Denchev C.

Two new smut fungi on Ventenata (Poaceae): Tilletia elizabethae from Slovakia and T. ventenatae from Turkey

Abstract: Two new smut fungi on Ventenata (Poaceae), Tilletia elizabethae (Tilletiaceae) on V. dubia from Slovakia, and T. ventenatae on V. subenervis from Turkey, are described and illustrated. They differ from all other Tilletia species by specialization on Ventenata. Tilletia elizabethae is distinguished from T. ventenatae by having larger spores and a dark cinnamon spore mass, while the spore mass of T. ventenatae is very dark reddish brown. Citation: Denchev T.

Tilletia tripogonellae (Tilletiaceae), A New Smut Fungus on Tripogonella spicata (Poaceae) from Argentina

A new smut fungus from Argentina, Tilletia tripogonellae T. Denchev & Denchev (Tilletiaceae), on Tripogonella spicata (Poaceae : Cynodonteae), is described and illustrated. It differs from all other species of Tilletia by being specialized on Tripogonella. Morphologically it differs from other known species of Tilletia on host plants from the subtribe Tripogoninae (Tilletia eragrostiellae, T. poonensis, T. savilei, T. tripogonis) by having a reticulate (vs. tuberculate or echinate) spore wall. A key to the smut fungi, that infect Eragrostiella, Tripogonella, Oropetium, and Tripogon, is provided.
