https://en.wikipedia.org/wiki/Triphragmium_ulmariae
The fungus grows in the petioles and/or midribs of the perennial plant meadowsweet (Filipendula ulmaria), a member of the rose family, causing swelling and distortion. Sori develop with bright orange spores. The rust's spores reach the new meadowsweet plants via air movements. The rust has a severe effect on the survival of meadowsweet seedlings.
