In December, 1922, Sir John Russell called the writer's attention to some diseased potatoes which had been sent to the Rothamsted Experimental Station. Dr. W. B. Brierley, Head of the Mycology Laboratory, had examined them and had failed to find evidence of fungal attack though the diseased areas bore a superficial resemblance to the appearances presented by “blight” affected potatoes due to Phytophthora infestans. He had, however, found numerous eelworms in the diseased tissues and because of this the writer was asked to examine the material.
