Resumen de "Entyloma crepidis-tectori" and "Urocystis deschampsiae", two new smut fungi from Europe
Two new smut fungi (Ustilaginomycetes) are described and illustrated from Europe: Entyloma crepidis-tectori M. Pi¹tek sp. nov., causing leaf spots on Crepis tectorum L. in Denmark, and Urocystis deschampsiae M. Pi¹tek sp. nov., forming long striae between the veins of Deschampsia caespitosa (L.) P. Beauv.
in Iceland. E. crepidis-tectori is the third Entyloma de Bary species known on Crepis L. (Asteraceae). The species is similar to E. zacintha Vánky infecting Crepis zacintha (L.) Loisel. in Greece, from which it differs by possessing larger, commonly irregular spores with a slightly thicker spore wall. U. deschampsiae is the first Urocystis Rabenh. ex Fuckel species on Deschampsia P. Beauv., but the eighth Urocystis infecting grasses belonging to the subtribe Aveninae (Poaceae). The new species differs from all of them by the number and frequency of spores per spore ball as well as by the sizes of the spore balls, spores and/or sterile cells.
