Triphragmium ulmariae
Template:Short description Template:Speciesbox
Triphragmium ulmariae is a species of rust fungus in the family Sphaerophragmiaceae. It causes meadowsweet rust gall,[1]Template:R/superscript which develops as a chemically induced swelling, arising from the lower surface of the meadowsweet (Filipendula ulmaria) leaves.[2]Template:R/superscript
Life cycle
The fungus grows in the petioles and midribs of the perennial plant meadowsweet (Filipendula ulmaria), a member of the rose family, causing swelling and distortion. Sori develop with bright orange spores.[2]Template:R/superscript The rust's spores reach the new meadowsweet plants via air movements.
The rust has a severe effect on the survival of meadowsweet seedlings.
