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.

Abstract A description is provided for Phoma sorghina. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Gramineae and all kinds of plants. Also isolated from soil, air and various animal sources. DISEASE: A minor leaf spot of cereals and grasses. The visible symptoms vary considerably; on sorghum leaves spots are usually irregular or rounded, yellowish-brown or grey with definite reddish-purple margins or indefinite in outline, reaching 1 cm or more in width. Pycnidia develop within spots on leaves, glumes and seeds. Also the fungus has been implicated with pre- and post-emergence death of seedlings of Macroptilium and Sylosanthes species (54, 1779) crown rot of bananas (61, 3556), leaf spot of Agave americana and stem rot of Euphorbia tirucalli (63, 3383), brown stem canker of Leucosperum cordifolium (56, 253). GEOGRAPHICAL DISTRIBUTION: A ubiquitous fungus occurring in tropical and subtropical regions. Africa (Botswana, Cameroon, Egypt, Ethiopia, Gambia, Kenya, Malawi, Mauritius, Mozambique, Nigeria, Senegal, Sierra Leone, South Africa, Sudan, Tanzania, Togo, Uganda, Zaire, Zambia, Zimbabwe); Asia (Bangladesh, Brunei, Burma, China, Hong Kong, India, Indonesia (Irian Jaya), Laos, Malaysia, Nepal, Pakistan, Saudi Arabia, Sri Lanka, Taiwan, USSR); Australasia and Oceania (Australia, Hawaii, New Zealand, Papua New Guinea, Solomon Islands); Europe (Germany, Portugal, Italy, UK); North America (Canada, USA); Central America and West Indies (Antigua, Guatemala, Honduras, Jamaica, Nicaragua, Puerto Rico, Trinidad); South America (Argentina, Bolivia, Brazil, Colombia). TRANSMISSION: Probably by contaminated seed; the fungus has been found on or isolated from several seed samples (1, 289; 33, 599; 47, 2153; 54, 1779; 60, 367; 61, 4102). In Taiwan P. sorghina has been found to be transmitted from seed to seedlings (62, 4281). The fungus has also been claimed to persist on trash and weed hosts and remain viable up to 1 yr but lose its viability after 2 yr storage on dry infected leaves (Koch & Rumbold, 1921).

Abstract A description is provided for Pseudocercospora timorensis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Ipomoea batatas (sweet potato), I. biloba, I. campanulata, I. cordofana, I. muricata, I. peltata, I. setifera.DISEASE: Leaf spot or brown leaf spot of sweet potato. Small circular lesions first form on the leaf borders and tips before spreading over the leaf surface. These leaf spots enlarge becoming brown to dark brown in colour with a verruculose surface. The larger leaf veins may delimit the spots. GEOGRAPHICAL DISTRIBUTION: Africa: most countries; Asia: Hong-Kong, India, Indonesia, Malaysia, Taiwan; Australasia: Fiji, Papua New Guinea, Solomon Islands; North America: West Indies (St Lucia). TRANSMISSION: Presumably by wind-borne and water-splash dispersed conidia.
