Creeping Thistle Rust - Puccinia punctiformis
This rust causes galls on Creeping Thistle (Cirsium arvense), and the whole plant appears stunted. There is no host alternation. Sickly-smelling yellow spermogonia are followed by brown aecia covering the leaf underside; light brown uredinia and darker brown telia are present later.
It overwinters as mycelium in the root stock and can kill the thistle plant before flowering. It can be transmitted by insects.
Common and widespread in Britain.
Common in Leicestershire and Rutland.
