Abstract A description is provided for Cercospora carbonacea. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Dioscoria spp. DISEASE: Leaf spot of yams. Causes fairly large, 5-20 mm, angular leaf spots, which are usually delimited by the leaf veins. The dark brown to almost black leaf spots give an almost charred appearance to the leaves, while on the lower surface the spots are grey becoming brown with age. GEOGRAPHICAL DISTRIBUTION: Africa: Ethiopia, Ghana, Guinea, Nigeria, Sierra Leone, Tanzania, Togo, Asia: Burma, India, North America: Canada (Ontario), West Indies (Barbados, Grenada, Jamaica, St. Vincent, Puerto Rico, Trinidad); South America: Venezuela. TRANSMISSION: Presumably by wind-borne and rain-splash dispersed conidia, surviving adverse periods in crop debris.

DISEASE: Leaf spot or brown leaf spot of Hibiscus spp. The first symptoms are yellowish patches on the leaf surface. These then become necrotic and gradually expand into irregular greyish brown leaf spots with dark brown to purple borders, surrounded by a pale yellow halo. Ultimately the necrotic areas become shrivelled and crack (30, 445). GEOGRAPHICAL DISTRIBUTION: The fungus is found wherever Hibiscus is cultivated (Chupp & Sherf, 1960). Africa: Ethiopia, Ghana, Mauritius, Sierra Leone, South Africa, Sudan, Tanzania, Uganda, Zimbabwe; Asia: Borneo, India, Indonesia, Japan, Malaysia, Philippines; Australasia: Fiji, Papua New Guinea; North America: West Indies (Jamaica, Trinidad, Cuba); South America: Colombia, Venezuela.

Abstract A description is provided for Cintractia axicola. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Fimbristylis species, including F. annua, F. autumnalis, F. complanata, F. dichotoma, F. diphylla, F. exilis, F. globulosa, F. obtusispora, F. squarrulosa, F. tenera and F. thonningiana; occasionally other Cyperaceae. DISEASE: Smut of Fimbristylis. Dikaryotic hyphae ramify intercellularly and intracellularly in the epidermis, cortex, medulla and vascular tissues of infected peduncles and form a white fungal covering; within this covering the fungal stroma with sporogenous pockets develops. Eventually the smut forms conspicuous black spore masses around the peduncles, whilst the spikelets are little altered morphologically. GEOGRAPHICAL DISTRIBUTION: Widespread in tropical and subtropical regions. Africa: Gabon, Ghana, Mauritius, Nigeria, Sierra Leone, South Africa, Tanzania, Uganda, Zaire, Zambia, Zimbabwe; Asia: Burma, China, India, Indo-China, Japan, Malaysia, Pakistan, Philippines, Sri Lanka, Taiwan; Australasia and Oceania: Australia, Fiji, Papua New Guinea, North America: Mexico, USA; South America: Argentina, Brazil, Chile, Colombia, Ecuador, Uruguay, Venezuela; Central America: Costa Rica, Cuba, Dominica, Grenada, Jamaica, Panama, Puerto Rico, Dominican Republic, St. Kitts, St. Lucia, St. Thomas, St. Vincent, Tobago, Trinidad, Virgin Is. (IMI Distribution Map 626, 1991). TRANSMISSION: Infection occurs in individual inflorescences. Ustilospores (and basidiospores) are disseminated by wind and rain. Ustilospore germination on peduncle surfaces and direct penetration of the epidermis have been observed (48, 3370).
