Triphragmium ulmariae is a species of fungus in the Sphaerophragmiaceae family. It causes meadowsweet rust gall, which develops as a chemically induced swelling, arising from the lower surface of the meadowsweet leaves.
Cause
This common gall is caused by the foliar 'rust' fungus Triphragmium ulmariae (DC.) Link, 1825 .[3]
Appearance
The fungus attacks the petioles and / or midribs of the perennial meadowsweet (Filipendula ulmaria) plant, a member of the Rosaceae family, causing swelling and distortion. Sori develop with bright orange spores.[3]
Life cycle
The rust's spores reach the meadowsweet via air movements and are spread from the galls that develop on the petioles and / or midrib veins.
Infestation
The rust has a severe effect on the survival of meadowsweet seedlings.
