Additions to Ramularia species (hyphomycetes) in Poland

The morphology and revised distribution of three Ramularia species (teleomorphs unknown) are presented based on fresh specimens. Ramularia melampyri is new for Poland, and R. celastri is reported from its third (and easternmost) locality in Europe. Ramularia abscondita specimens confirm the occurrence of this species in Poland. As R. melampyri hosts (Melampyrum spp.) are currently classified in Orobanchaceae, the implications of the new systematics of Scrophulariaceae s.l. for the taxonomy of Ramularia and related Mycosphaerella species are discussed briefly.
