Popis:	A form of Melampsora rust was found to cause stem cankers on Salix viminalis clones in south-west England. Comparative studies suggested that the rust differed from the leaf-infecting form (M. epitea var. epitea f. sp. larici-epitea typica) by causing infection of both young stems and shoot tips, having distinct host specificity, and existing predominantly as the uredinial stage. After incubation for a period at low temperature the rust produced only poorly developed hypophyllous telia similar to those of the leaf-infecting form. In the field, this form of rust overwintered in buds or cankered stems of infected willows. Survey results of willow plantations in the U.K. in 1991 showed that the stem-infecting form occurred in most study sites including Northern Ireland and Scotland. The leaf-infecting form was present in all locations, whereas M. ribesii-viminalis was occasionally found only in south-west England.
