Abstract A description is provided for Urocystis violae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Cultivated and wild violets, principally Viola odorata, also V. adunca, V. alba, V. biflora, V. glabella, V. grypoceras, V. longipes, V. lutea, V. nuttallii, V. reichenbackiana, V. riviniana, V. tricolor, V. turkestanica and other Viola spp. and hybrids. DISEASE: Leaf and stem smut of Viola spp. GEOGRAPHICAL DISTRIBUTION: Asia: Cyprus, Japan, USSR (Republic of Georgia, Turkestan). Europe: widespread, including Austria, British Isles, Czechoslovakia, Denmark, Finland, France, Germany, Italy, Netherlands, Poland, Romania Sweden, Switzerland, USSR (Estonia), Yugoslavia, possibly extending into north Africa. North America: Canada, USA. TRANSMISSION: Infection is perennial in the rootstock. New infections are initiated from ustilospores which survive in decaying plant parts and in soil. Transmission by seed has been reported (5, 34) but is presumably rare.

Abstract A description is provided for Ustilago heufleri. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Erythronium oregonum, E. americanum, Tulipa sylvestris, T. edulis, T. eichleri, T. saxatilis and other species or hybrids of Tulipa and Erythronium.DISEASE: Leaf smut of Erythronium and Tulipa spp. GEOGRAPHICAL DISTRIBUTION: Asia: China, Turkey, USSR (Republic of Georgia). Europe: including Austria, British Isles, Czechoslovakia, Germany, Greece, Romania, Yugoslavia. North America: Canada, USA. TRANSMISSION: No recent detailed studies have been reported. Ustilospores survive on infected plant remains and in the soil and germinate to infect the new season's leaves, usually at the time of their emergence from the soil. The sporadic nature of disease outbreaks suggests that bulbs can carry infection which may remain latent for a period of several years.

Abstract A description is provided for Leucostoma cinctum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Leucostoma cinctum, especially in its conidial state, is a well-known pathogen of stone-fruit trees causing necrosis of twigs, perennial Cytospora-canker. The fungus penetrates mainly through the scars, and may result in dieback of branches or even whole trees. Tree susceptibility to L. cinctum is influenced by lesions (Stanova, 1990). Comparative anatomy and host response of peach cultivars inoculated with L. cinctum was studied by Biggs (1986). Resistance of different cultivars of stone-fruit trees to L cinctum has been investigated by many authors (Cociu et al., 1991; Miles et al., 1989; Pedryc & Rozsnyai, 1991). HOSTS: On dead or dying, attached or fallen twigs of the Rosaceae, mainly Prunoideae (Amygdalus, Armeniaca, Cerasus, Persica, Prunus) and rarely other subfamilies of the Rosaceae, including genera such as Cotoneaster, Crataegus, Malus and Pyrus. GEOGRAPHICAL DISTRIBUTION: Asia: Armenia, Republic of Georgia, Iran, Kazakhstan, Russia, Turkmenistan, Uzbekistan. Australasia: Australia. Europe: Czech Republic, France, Germany, Hungary, Italy, Moldova, Rumania, Russia, Slovakia, Spain, Switzerland, Sweden, Turkey, UK, Ukraine, former Yugoslavia. North America: Canada, USA (Idaho, Michigan, New-Jersey, Oregon). TRANSMISSION: Both conidia and ascospores are air-borne, especially under humid conditions. Orange or reddish droplets or tendrils of conidia extruded from conidiomata can be often seen after rain. It is also known that arthropods can carry propagules in stone-fruit orchards (Helton et al., 1988).

Abstract A description is provided for Valsa malicola. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Valsa malicola is associated with dieback of Malus twigs, especially weakened by other factors, for example when frozen, burnt, wounded, injured by insects or attacked by other pathogens. HOSTS: On dead or dying twigs of Malus species, and other Maloideae (Cotoneaster, Crataegus, Cydonia, Pyracantha, Pyrus, Rosa). The fungus can also be found on other members of the Rosaceae (e.g. Prunus), but only infrequently, and mainly as the anamorph. GEOGRAPHICAL DISTRIBUTION: Asia: Armenia, Azerbaijan, China, Republic of Georgia, Kazakhstan, Russia. Europe: Austria, Czech Republic, Germany, Italy, Latvia, Lithuania, Portugal, Rumania, Russia, Slovakia, Sweden, Switzerland, UK, Ukraine. North America. TRANSMISSION: Both conidia and ascospores are air-borne, especially under humid conditions. Brightly coloured droplets or tendrils of conidia are often exuded from conidiomata after rain.

Abstract A description is provided for Entyloma serotinum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Symphytum spp., including S. asperrimum, S. bulbosum, S. cordatum, S. officinale, S. ottomanum and S. tuberosum; Borago officinalis; also recorded on Amsinckia, Lappula and Mertensia spp. (in USA) and Pulmonaria (in Europe, but see 64, 4163). DISEASE: Leaf spot of Symphylum, less frequently (though with similar symptoms) of other members of the Boraginaceae.GEOGRAPHICAL DISTRIBUTION: Africa: Algeria. Asia: Israel, USSR (Republic of Georgia). Australasia: New Zealand. Europe: widespread, including Austria, British Isles, Czechoslovakia, Denmark, France (including Corsica), Germany, Hungary, Italy, Netherlands, Poland, Portugal, Romania, Spain, Switzerland, USSR (Latvia), Yugoslavia. North America: USA. TRANSMISSION: Ustilospores survive on infected plant remains and in soil, and germinate to infect seedlings and the new seasons's leaves. In Europe conidia may also over-winter and initiate new infections in spring (Kaiser, 1936). During the growing season, conidia are disseminated by air currents and water-splash.

Abstract A description is provided for Valsa sordida. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Valsa sordida is usually associated with Valsa canker of poplar twigs. Wounded trees, and trees injured by insects or attacked by other pathogens are more susceptible to infection. Development of Valsa canker is affected by environmental stress (Guyon, 1996; Tao et al., 1984). Poplar canker caused by V. sordida has been studied in different countries (CMI Distribution Maps of Plant Diseases, 1977; Worrall, 1983; Wang et al., 1981) The fungus can be often found in declining poplar stands together with another pathogen of poplar trees, Leucostoma niveum. Valsa sordida may also cause necrosis of willow twigs. HOSTS: Populus spp., Salix spp. and, more rarely, other woody angiosperms. GEOGRAPHICAL DISTRIBUTION: Africa: Morocco. Asia: Armenia, Azerbaijan, China, Republic of Georgia, India, Iran, Iraq, Israel, Japan. Kazakhstan, Korea, Russia (Tatarstan), Turkey, Turkmenia, Uzbekistan. Australasia: Australia (Victoria), New Zealand. Europe: Austria, Belgium, Bulgaria, Czech Republic, Denmark, Estonia, France, Germany, Greece, Ireland, Italy, Netherlands, Norway, Poland, Portugal, Rumania, Russia, Slovakia, Sweden, Switzerland, UK, Ukraine, former Yugoslavia. North America: Canada (Alberta, British Columbia, Nova Scotia, Ontario, Québec, Saskatchewan). USA (California, Colorado, Michigan, Minnesota). South America: Chile. TRANSMISSION: Both conidia and ascospores are air-borne, especially under humid conditions. Yellow or orange exudation of conidia from conidiomata can be often seen after rain.
