Abstract: Sclerotinia cirsii-spinosissimi is described as a new species from bracts of Cirsium spinosissimum based on morphological, cultural and molecular studies. Ascospore size and absence of small lipid bodies inside the spores are distinctive, medium sized sclerotia are typically produced on solid media in cultures. This description includes earlier molecular studies showing a close relationship to S. borealis. A key is added to Sclerotinia species from arctic-alpine habitats
