Soyabean leaves artificially inoculated with basidiospores of T. cucumeris (AG-2-3 of Rhizoctonia solani) developed at first, primary lesions, then, secondary lesions and eventually, irregular large-sized lesions. The germ tubes of the germinating basidiospores formed appressoria and their infection pegs penetrated into the epidermal cells. A stroma-like structure was produced within the invaded tissues.
