Abstract
Rhytisma polaris, which causes tar spot disease on Salix polaris on Spitsbergen Island, is described. The most characteristic morphological feature of this new species are ascospores distinctly broader than those of other Rhytisma species. rDNA ITS and LSU sequence analysis also indicated that R. polaris is sufficiently distinct from other Rhytisma species to justify the new species status.
