Abstract A description is provided for Dilophospora alopecuri. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On culms, flowering shoots and leaves of grasses and cereals (wheat, oats, rye, barley). DISEASE: Twist of grasses. GEOGRAPHICAL DISTRIBUTION: Europe, Asia (India, Iraq, Pakistan), N. America (Canada, USA), Australia and New Zealand. TRANSMISSION: By splash-dispersed air-borne conidia during the growing season. Perennation by infected plant debris, soil and seed. Observations in the Netherlands (4, 140) and Russia (32, 415) led to the belief that nematodes (Anguillulina spp.) were important vectors of the fungus, but evidence elsewhere shows that this is unlikely (8, 300; 13, 20; 14, 296).

Abstract A description is provided for Fusarium flocciferum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Isolated from soil. Also occurs on the roots of a wide range of plants, including temperate cereals (Hordeum, Triticum), legumes (Lupinus, Pisum, Vicia), cucurbits (Cucumis sativus), and others such as carrot (Daucus carota) and beet (Beta vulgaris); sometimes occurs in association with nematodes. DISEASE: Not regarded as an aggressive pathogen, but in association with nematodes may cause root lesions, damping-off, root, tuber or bulb rots. Reported to cause disorders of cultivated mushroom beds. Occasionally causes skin infections of animals (one IMI record from crocodile's tail). GEOGRAPHICAL DISTRIBUTION: Widespread but infrequent, apparently more common in temperate regions. Reported from Asia: Bhutan, China, India, Iran, Turkey; Australasia: New Zealand; Europe: Denmark, Germany, The Netherlands, Poland, Turkey (W), UK; North America: Canada, USA. TRANSMISSION: Conidia are dispersed locally by water flow and splash droplets. Chlamydospores may be transported by movement of soil or infected plant debris. It may also be seed-borne (71, 1568).

Abstract A description is provided for Phialophora asteris. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Aster novi-belgii cultivars (michaelmas daisy) and, more rarely, A. tradescantii. Cultivars of Callistephus chinensis are also very susceptible with A. amellus, A. linosyris and Bellis perennis moderately so; A. acris and A. novae-angliae appear to be resistant (Burge & Isaac, 1974). DISEASE: Vascular wilt of michaelmas daisies, aster wilt. GEOGRAPHICAL DISTRIBUTION: Europe (UK, Netherlands, Denmark); New Zealand. TRANSMISSION: Presumably by splash dispersed conidia and by infected plant debris in the soil.

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 Peronospora anemones. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Anemone coronaria, A. globosa. DISEASE: Downy mildew of anemones. Infected leaves lose their natural bloom, appearing dull green, almost grey in colour and are often down curled giving the plant a rounded appearance. As the disease progresses, leaf colour may change to shades of pink or purple with necrotic areas appearing on the older leaves. Invasion by secondary organisms (e.g. Botrytis cinerea) is common, especially after frost or storm injury, and this accelerates plant death. In favourable conditions conidiophores develop forming a whitish-grey down on the lower leaf surface, on the bracts and, less frequently, on the petioles. It is not uncommon for affected plants to show little or no sporulation and in these cases the presence of extensive intercellular mycelium and, later in the season, oospores in petioles and peduncles helps diagnosis. GEOGRAPHICAL DISTRIBUTION: Australasia (New Zealand); Europe (England, Jersey, France, Italy, Netherlands). TRANSMISSION: Primary infection is caused by oospores in plant debris in the soil. Tramier (1963) was unable to germinate oospores and thus work out precise details of the conditions affecting their germination but he showed evidence that regular and prolonged rain encouraged germination. Conidia, which cause secondary infections, are dispersed by rain and during harvesting of the flowers. Wind is thought to be unimportant in their dissemination as shown by glass slides covered with vaseline and placed near an infected crop (Tramier, 1965).
