The modes of teliospore germination of Ustilago trichophora (Link) Kunze ex Körnicke occurring in Poland
Ustilago trichophora affects <em>Echinochloa crus-galli </em>and other species of <em>Echinochloa </em>genus. <em>U. trichophora </em>is a member of the order Ustilaginales, of which the germinating teliospores form a promycelium with sporidia. Investigations by Ingold (1996) proved that spores coming from various parts of the world germinate in a different way. The aim of the investigation was to determine the mode of germination of <em>U. trichophora </em>spores found in Poland.
