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 Didymella bryoniae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Cucurbits (Bryonia, Colocynthis, Cucumis, Cucurbita, Luffa, Momordica and Trichosanthes). DISEASE: Gummy stem blight of Cucurbitaceae, showing a variety of symptoms which are referred to as leaf spot, stem canker, vine wilt and black fruit rot. Lesions on leaves and fruit usually begin as spreading water-soaked areas; in the former these may have a chlorotic halo, become light brown and irregular in outline, leaves can be destroyed. On fruit, dark cracked sunken lesions form, beneath which an extensive rot is found. In the field the first symptoms may be plant collapse where sunken, girdling cankers lead to total loss. Infection also occurs on seedlings. The main characteristic features are the gummy exudate on stem and fruit lesions and the abundant pycnidia followed by perithecia, GEOGRAPHICAL DISTRIBUTION: Widespread (CMI Map 450, ed. 2, 1970). Records not yet mapped are: Brunei, Mexico, Netherlands, Pitcairn Islands, Republic of Ireland, Salvador. TRANSMISSION: Through conidia by water splash and aerially by ascospores which, in glasshouses in England, had a diurnal periodicity with a peak at 1800-2000 hr (46, 825; 48, 672); and in USA occurred mostly at night (50, 2621). Both spore types may serve as primary inoculum and between-crop survival is an important factor in the epidemiology. Reports on seed transmission are conflicting in cucumber, although seed could be inoculated successfully, no evidence for natural infection was found (48, 322). In the glasshouse transmission by pruning knives has been demonstrated (46, 825).

Abstract A description is provided for Meliola capsicola. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Meliola capsicola produces chlorotic zones in the leaves, under and around the colonies. A strong attack might thus result in reduction of photosynthetic capability.

Abstract A description is provided for Pestalotiopsis mangiferae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Mangifera indica; also on Anacardium occidentale, Combretum decandrum, Eucalyptus spp., Mimusops spp., Vitis vinifera and many other unrelated host plants. DISEASE: Grey leaf spot of Mangifera indica. The spots vary in size from a few mm to several cm in length, are usually sharply delimited by a dark, raised border, and are silvery grey above and grey to brown below; leaf spots on other hosts are similar. Brown spot or rot of mango fruits is also known. GEOGRAPHICAL DISTRIBUTION: Ghana, Nigeria, Sierra Leone, Tanzania, Uganda, Zaire, Zambia; Bangladesh, Brunei, Burma, Hong Kong, India, Malaysia, Nepal, Sabah, Solomon Islands, Sri Lanka; Australia; Dominican Republic; Venezuela. TRANSMISSION: Inoculation studies with conidia and mycelium have shown P. mangiferae to be a weak parasite, capable of infecting young injured leaves, injured fruits, older uninjured leaves and healthy fruits if in contact with diseased tissue (35, 378; 40, 421). It has been isolated from soil, but the possibility of transmission through soil has not been investigated.
