Abstract A description is provided for Acremonium zonatum . Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Known from leaves of Amaranthus gangeticus, Annona squamosa, Boehmeria nivea, Brillantaisia nitens , Calopogonium mucunoides, Coffea arabica, C. liberica-excelsa, C. robusta, Colocasia esculenta, Coridia dentata, Crotalaria anagyroides, Cucumis sativus, Eichhornia crassipes, Eranthemum nervosum, Erythrina senegalensis, Ficus carcia (var. celeste ), Hypoestes verticillaris, Kosteletzkya grantii, Lindackeria bahobensis, Litchi chinensis, Momordica foetida, Morus acidosa, Musa sapientum, Pachira insignia (syn. Bombax sessile ), Phaseolus atropurpureus, Plumeria alba, Solanum verbascifolium, Steriospermum bantharum and Vigna sinensis . DISEASE: Causal agent of 'fig zonate spot' and 'zonal leaf spot' of coffee but forming similar zonate leaf spots on a wide range of phanerogams (see above). GEOGRAPHICAL DISTRIBUTION: Widespread in tropical countries and known from Africa (Ghana, Guinea, Nigeria, Sierra Leone, Sudan, Tanzania, Zaire), Asia (Bangladesh, Brunei, India, Malaysia (Sabah, Sarawak), New Guinea, Taiwan, Western Samoa), West Indies (Jamaica, Puerto Rico, Windward Islands), Central America (Costa Rica), North America (USA, southern Louisiana), and South America (Peru, Venezuela). TRANSMISSION: Presumably mainly by rain splash but insects crawling over infected leaves could play some part. Old diseased foliage on the ground is probably the primary source of infection (28, 180). Inoculations by spraying spore suspensions and placing cultures on lower leaf surfaces successful (Tims & Olive, 1948).
