CANADIAN SPECIES OF SYNCHYTRIUM

Abstract
Twenty collections of Synchytrium from various parts of Canada were studied, and among these were S. perforatum, S. athyrii, S. rubrocinctum, S. cupulatum, and S. aureum. This is the first report of S. athyrii, S. rubrocinctum, and S. cupulatum from America. In addition to these five species, 13 short-cycled ones are described. These cannot be identified with certainty at present from the material at hand, and are not given specific names. Most of them occur on new hosts in new localities, and the collection of them greatly extends the known geographical and host range of Synchytrium.
