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.
Contents
Cause
This common gall is caused by the foliar 'rust' fungus Triphragmium ulmariae (DC.) Link, 1825 .
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.
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.
