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 Coccomyces strobi. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pinus ayacahuite, P. excelsa [= P. wallichiana] (twig), P. monticola (twig), P. strobus (twig), P. wallichiana. Most records are on P. strobus. DISEASE: Coccomyces strobi is found on recently killed twigs of 5-needle pines. Sherwood (60, 1319) noted that 'since the fungus is nearly ubiquitous and appears soon after the death of the portions of the host on which it occurs, it is tempting to brand it as parasitic'. The twigs on which it occurs are typically rather brittle, suggesting that, like Therrya fuckelii (IMI Description 1297), T. pini (IMI Description 1298) and Colpoma quercinum (IMI Description 942), this fungus may have a rôle in self-pruning of the tree. GEOGRAPHICAL DISTRIBUTION: Canada (British Columbia, New Brunswick, Nova Scotia, Ontario), Hungary, Ukraine, USA (Connecticut, Georgia, Maine, Maryland, Massachusetts, Michigan, Minnesota, Nebraska, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Virginia, Washington, Wisconsin). European records are on Pinus strobus, a native of North America. The fungus is thus most probably also to be a native of North America, which has travelled to Europe with its host. The record from Ukraine is tentative, based on a collection with rather old ascomata. The record from Washington State on P. monticola appears to be the first from west of the Rockies. TRANSMISSION: By air-borne ascospores in humid conditions; in the USA, ascomata containing ascospores have been observed from May to August.

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.
