• Fungi on and in roots of continuously cropped upland rice were examined. Dominant fungi on the root surfaces were found to be composed of limited genera : Fusarium, Penicillium, and Pyrenochaeta. Among them, only Pyrenochaeta sp. was remarkable in regard to continuous cropping of upland rice. The results showed that Pyrenochaeta sp. penetrated into and multiplied in root tissues of aged plants and could survive during the winter on infected root residues left in the field, and in the next spring colonized the root surfaces of new seedlings, and then penetrate into root tissues and thus be accumulated on and in roots by the continuous cropping of upland rice. Pyrenochaeta sp. was also found to have a considerable specific affinity for roots of upland rice, compared with the roots of several other plants.
