U. deyeuxiae is close to U. scrobiculata Liro from which it differs in having more complete and higher ustilospore reticulations. New to China are: 1) Ustilago oxadalis Ellis & Tracy on Oxalis corniculata L., 2) Ustilago Polygoni-alati Thirum. & Pavgi on Polygonum nepalense Meisn., and 3) Urocystis melicae (Lagerheim & Liro) Zundel on Melica radula Fr. A revised description of Ustilago polygoni-alati is given.
