Abstract A description is provided for Doassansia sagittariae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Sagittaria species, including S. sagittifolia, S. calycinus, S. cuneata, S. graminea, S. heterophylla, S. lancifolia, S. latifolia, S. montevidensis, S. natans. DISEASE: Leaf spot of Sagittaria species. The round or sometimes vein-limited, angular, spots often cover a large proportion of the leaf surface and are then very conspicuous. The disease usually appears on the plants year after year and is present throughout the vegetative season of the host, athough most obvious in the later part of that season. GEOGRAPHICAL DISTRIBUTION: Widespread in north temperate regions (33, 634). Europe: Austria, Belgium, Czechoslovakia, Denmark, Finland, France, Germany, Hungary, Italy, Latvia, Netherlands, Poland, Romania, Russia (European region), Sweden, Switzerland, UK, Ukraine; Asia: Russia (Republic of Georgia, Kazakhstan, Siberia, Yakutskaya ASSR; Ul'yanishchev, 1952); North America: Canada (British Columbia, Manitoba, Ontario, Saskatchewan; 46, 3383), USA (central states, north east states; Arkansas, Connecticut, Delaware, Florida, Illinois, Indiana, Kansas, ME, Missouri, MT, North Dakota, New York, Ohio, South Dakota, Texas, Vermont, Wiskonsin, Wyoming; 69, 2765); South America: Argentina. TRANSMISSION: From the habitat of the host plants water is assumed to be important in dissemination and infection. Germination of ustilospores either before or after release of spore balls by decay of host leaves inevitably results in presence of basidiospores in water. Liro (1938) suggested the probability of a saprophytic, budding phase in water, followed by early stages of host infection under water, but no detailed studies have been reported.

Abstract A description is provided for Ustilago longissima. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Species of Glyceria, including G. maxima, G. fluitans, G. grandis, G. multiflora, G. nemoralis, G. obtusa, G. plicata, G. striata. DISEASE: Leaf stripe smut of Glyceria. Infected plants are slightly stunted, pale or yellowish-green, and usually fail to flower. Sporulation can occur throughout the growing season of the host. GEOGRAPHICAL DISTRIBUTION: Widespread, especially in north temperate regions. Asia: India (Nilgiri Hills), USSR (Siberia); Europe: Austria, Bulgaria, Czechoslovakia, Denmark, Finland, France, Germany, Hungary, Italy, Netherlands, Norway, Poland, Romania, Spain, Sweden, Switzerland, UK, USSR (Estonia, Republic of Georgia, Latvia, Russia), Yugoslavia; North America: Canada (Alberta, British Columbia, Man, NS, Ont, Que, Sask), USA (Connecticut, Colorado, Idaho, Illinois, Iowa, ME, Maine, Michigan, MN, MT, Nebraska, New Hampshire, New York, North Dakota, Oregon, Pennsylvania, Utah, Vermont, Washington State); South America: Argentina. TRANSMISSION: No detailed studies have been reported. The powdery ustilospores are readily disseminated by wind and water. Seed transmission is considered unlikely.

Abstract A description is provided for Ustilago hypodytes. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: A wide range of grasses, including species of Agropyron (many), Ammophila, Brachypodium, Bromus, Calamagrostis, Diplachne, Distichlis, Elymus (many), Festuca, Glyceria, Hilaria, Hordeum, Haynaldia, Lygeum, Melica, Orysopsis, Panicum, Phalaris, Phleum, Poa (many), Puccinellia, Secale, Sitanion, Sporobolus, Stipa (many), and Trisetum. DISEASE: Stem smut of grasses. GEOGRAPHICAL DISTRIBUTION: Chiefly a temperate species found in Europe (including Denmark, Finland, France, Germany, Hungary, Italy, Romania, Sweden, Switzerland, UK, USSR, Yugoslavia) and North America (Canada, USA) and extending to central and South America (Argentina, Peru, Uruguay), N. Africa (Libya, Morocco, Tunisia), Japan, Australia and New Zealand. TRANSMISSION: Not fully understood, though inoculation experiments have demonstrated that infection occurs in mature vegetative plants (possibly through meristematic tissue), not seeds or flowers (22, 240; 24, 511). Once established, infection is systemic, probably overwintering in the root system and spreading by vegetative multiplication of host plants as well as from plant to plant (24, 511; 19, 720).
