SUMMARY Methods by which the rust, Puccinia poarum , may be maintained on its alternate hosts, Tussilago farfara and Poa spp., are described. Telial material collected in the autumn requires extensive washing and drying before teliospores will infect Tussilago , but telial material collected after a winter in the field, in mid‐summer or from plants infected in the laboratory do not require this treatment. Infection of Poa pratensis and P. trivialis can readily be achieved from aeciospores or urediospores. Some advantages of this rust for research and teaching are stated.
