SUMMARY Two Strains of Rhizoctonia solani which were distinctly different in their morphological characters and their pathogenicity were isolated from wheat and wheat stubble. Isolate 1 had broad hyphae with large brown sclerotia usually produced on the aerial mycelium. Isolate 2 had narrow hyphae with small white sclerotia on potato dextrose agar and malt agar, but brown‐black sclerotia on oatmeal agar. It had a slower growth rate and a lower optimum temperature than isolate 1. In glasshouse experiments, isolate 1 produced sharp eyespot symptoms on winter wheat ‘Cappelle Desprez’ and a severe foot rot of broad beans. Isolate 2 produced both sharp eyespot and root rots of winter wheat.
