Abstract A description is provided for Ascochyta paspali. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Paspalum dilatatum (dallis grass), (and P. floridanum var. glabratum). DISEASE: Leaf blotch or streak of Paspalum spp. The visible symptoms are yellowish brown to grey lesions developing at the leaf tip and subsequently involving the entire leaf and sometimes the sheath. GEOGRAPHICAL DISTRIBUTION: Australasia (New Zealand); South America (Argentina) and North America (? USA). TRANSMISSION: The fungus occurs in Paspalum as an endophyte (Buchanan, 1984). The mycelium has been reported to grow systemically in xylem vessels of roots, leaves and inflorescences. Conidia are dispersed by rain splash and the fungus has been isolated from seeds. It has been suggested that the fungus might overwinter as mycelium within roots, crowns and infected seeds.

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).
