Six mono‐uredospore isolates (races) of Melampsora medusae Thiim. produced qualitatively distinct reactions, in vitro , when incubated at 15 °C on leaf disks of certain cultivars of Populus deltoides Marsh. The infection types in some race‐cultivar combinations were very temperature sensitive with less distinct reactions when incubated at 20 or 25°C. The significance of differential race‐cultivar‐temperature interaction in the epidemiology of M. medusae is discussed.
