• Microbotryum pinguiculae (Rostr.) Vánky on Pinguicula alpina L., a rarely collected smut fungus belonging to the genus Microbotryales in the class Urediniomycetes, is reported for the first time from the Carpathians as well as from Poland and Slovakia. The species is described and illustrated by a drawing of infected plants and SEM micrographs of spores. Microbotryum pinguiculae is a very rare fungus parasitizing various species of Pinguicula (Lentibulariaceae). It is known from Europe, Asia and North America, where it shows a true arctic-alpine type of distribution. Taxonomically its generic position is not completely stabilized and needs further studies employing modern techniques (e.g., molecular, ultrastructural).
