Puccinia poarum
The rust fungus Puccinia poarum galls the leaves of the alternate host, Colt's-foot (Tussilago farfara). The underside of the leaves have thickened areas bearing orange-red aecia and spermogonia.
The primary host is the meadow-grass, Poa, bearing yellow uredinia mainly on the leaf upperside and brown telia mainly on the underside.
Coleosporium tussilaginis also affects Coltsfoot, but is not a gall-causer
Widespread and locally frequent in Britain.
Status in Leicestershire and Rutland not known.
