Abstract A description is provided for Ustilago trichophora. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Echinochloa spp. including E. colonum, E. crus-galli, E. crus-galli var. frumentacea, E. crus-galli var. zelayensis, E. holubii, E. turneriana, E. walteri; occasional records on Panicum spectabile, Paspalidium geminatum, Sacciolopis striata, Tricholaene teneriffae. DISEASE: Loose smut or node smut of Echinochloa. Field symptoms vary from relatively inconspicuous infection of a few ovaries in an inflorescence, through node and culm infection with normal inflorescence production, to infections that result in production of rosettes of short leafy axillary shoots and no inflorescence or distortion of the entire shoot system. GEOGRAPHICAL DISTRIBUTION: Africa: Egypt, Malawi, Morocco, Nigeria, South Africa, Sudan, Tanzania, 'French Congo'; Asia: Azerbaijan, Burma, China, Republic of Georgia, India, Japan, Kazakhstan, Turkestan, Turkey, Uzbeckistan, 'Far East'; Australasia: Australia (NSW, NT, Qld.), New Zealand; Europe: Bulgaria, Czechoslovakia, Hungary, Italy, Lithuania, Moldova, Romania, Russia, Spain, Switzerland, Ukraine, Yugoslavia; North America: Canada (Quebec), Mexico, USA (range of E. crus-galli, Arkansas, California, Colorado, Connecticut, Washington DC, Delaware, Florida, IA, Idaho, Illinois, Indiana, Kansas, Louisiana, Maine, MD, Manitoba, Montana, North Carolina, Nebraska, New Hampshire, New Mexico, Nevada, New York, Ohio, Oklahoma, Oregon, Pennsylvania, South Dakota, Texas, Utah, Washington State, Wisconsin, Wyoming; 69, 2765); Central America and West Indies: Cuba; South America: Argentina, Venezuela. TRANSMISSION: The dusty spore mass is readily disseminated by wind or rain, enabling infection at various times in the host vegetative cycle. Infection is also sometimes seedborne.

Abstract A description is provided for Ustilago syntherismae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Digitaria spp., including D. filiformis, D. ischaemum, D. sanguinalis. DISEASE: Loose smut of Digitaria. Infection sometimes dwarfs the host and causes it to branch more profusely than usual (36, 657); it is also reported that vegetative vigour is much prolonged in infected plants compared with uninfected (30, 432). Surface contamination by the large number of ustilospores when shed may result in some discolouration of the entire inflorescence including sheaths and leaf blades. GEOGRAPHICAL DISTRIBUTION: Africa: 'Congo', Gambia, Kenya, Sierra Leone, South Africa, Sudan, Uganda, Zambia, Zimbabwe; Asia: Azerbaijan, China, Republic of Georgia, India, Japan, Pakistan, Russia (central Asia, far east); Australasia: Australia: NSW (31, 225); Europe: Bulgaria, Czechoslovakia, Denmark (39, 284), Germany, Hungary, Italy, Poland, Portugal, Romania, Russia (European region), Ukraine (52, 354); North America: Canada (Ontario; 46, 3383), Mexico, USA (Alabama, Arkansas, California, Connecticut, Washington DC, Delaware, Florida, Georgia, IA, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maine, MD, ME, Michigan, Montana, Missouri, MS, North Carolina, Nebraska, New Hampshire, New Jersey, New York, Ohio, Oklahoma, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Virginia; 69, 2765); South America: Argentina, Brazil, Uruguay. (33, 634; 40, 209; 48, 2203; 50, 2756; 64, 4163). TRANSMISSION: No detailed studies have been reported; ustilospores are presumably disseminated by air currents and infection is thought to be systemic.

Abstract A description is provided for Moesziomyces bullatus. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Echinochloa crus-galli. DISEASE: Seed smut of Echinochloa. The small number of sori in any infected inflorescence renders the disease inconspicuous and it is probably frequently overlooked. GEOGRAPHICAL DISTRIBUTION: Asia: Azerbaijan, China (Beijing, Chengtu), Kazakhstan, Japan, Russia (Far East, Siberia), Uzbekhistan; Australasia: New Zealand (57, 649); Europe: Bulgaria, Czechoslovakia, Denmark, Germany, Hungary, Italy, Poland, Portugal (39, 555), Romania, Russia (European region), Ukraine; North America: Canada (NS, Ontario; 46, 3383), Mexico, USA (eastern states, California, Colorado, Connecticut, Florida, Iowa, Illinois, Indiana, Louisiana, Maine, MD, North Carolina, Nebraska, New York, Pennsylvania, South Dakota, Wisconsin; 69, 2765). TRANSMISSION: No detailed studies reported.

Abstract A description is provided for Sphacelotheca hydropiperis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Polygonum hydropiper and many other species of Polygonum, mainly in section Persicaria. DISEASE: Flower smut of Polygonum. Infection is systemic. Hyphae in the flower stalk grow through the funicle into the ovule, from which the sorus develops leaving the perianth and stamens unchanged. Infected plants cannot normally set seed, but occasionally a portion of the inflorescence remains uninfected and some seed develops. GEOGRAPHICAL DISTRIBUTION: Widespread. Africa: Ethiopia; Asia: China, India, Indonesia, Japan, Nepal, Pakistan, Philippines, Sri Lanka, Taiwan, USSR (Central Asia, Turkestan); Australasia and Oceania: Australia, New Zealand, Papua New Guinea; Europe: Austria, Czechoslovakia, Denmark, Finland, France, Germany, Hungary, Iceland, Italy, Norway, Poland, Romania, Sweden, Switzerland, UK, USSR, Yugoslavia; North America: Canada (Newfoundland, NT, Nova Scotia, Ontario, Quebec); Greenland; Mexico; USA (Arkansas, California, Colorado, Connecticut, Delaware, Illinois, ME, Maine, Michigan, Montana, Missouri, Nebraska, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oregon, Pennsylvania, Rhode Island, Tennessee, Vermont, Virginia, Washington State, Wisconsin, Wyoming); South America: Argentina, Brazil, Chile, Colombia, Ecuador (33: 450 & 634). TRANSMISSION: Ustilospores dispersed by wind and water contaminate seed and soil and eventually germinate and infect new season's growth.
