Abstract A description is provided for Phoma insidiosa. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Sorghum spp., Oryza sativa, Saccharum officinarum, Setaria, Triticum aestivum and Zea mays. DISEASE: A minor leaf spot of Sorghum and Setaria spp. and other Gramineae. The macroscopic symptoms are variable and not particularly distinctive. Leaf lesions have an irregular outline, sometimes beginning at the tip or edge, and are brown to grey with narrow redish-purple margins. The scattered pycnidia occur sometimes in clusters or lines, interveinally. Spotting and pycnidia form on grain and glumes. GEOGRAPHICAL DISTRIBUTION: Argentina, Australia (W.), Brazil, Canada, China, Cuba, Ethiopa, Hawaii, India, Jamaica, Kenya, Laos, Malawi, Malaysia (W.), Nepal, Nigeria, Puerto Rico, Rhodesia, Senegal, Sierra Leone, South Africa, Sudan, Tanzania, Uganda, USA, USSR, Venezuela, Zaire Republic, Zambia. The fungus may be detected on introduced seed. TRANSMISSION: Probably carried on the seed; infection of the seed reduces both germination and subsequent growth. May remain viable on seed for 1 yr.

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).

Abstract A description is provided for Phakopsora gossypii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Gossypium acuminatum, G. arboreum, G. aridium, G. barbadense, G. brasiliense, G. herbaceum, G. mexicanum, G. microcarpum, Gossypium sp. (cult.), Azanza garckeana and Thespesia populnea. DISEASE: Cotton rust. Confined to the growing tissues, chiefly the leaves and spreading from the older parts to the new leaves as rapidly as they are formed causing premature defoliation. The attack is severe on weak plants. GEOGRAPHICAL DISTRIBUTION: Africa (Agalega Is. (near Mauritius), Congo, Ghana, Ivory Coast, Kenya, Mauritius, Nigeria, Sierra Leone, Somalia, South Africa, Tanzania, Uganda); Asia (Burma, Cambodia, Ceylon, China, Fiji, Formosa, India, Java, New Guinea, New Caledonia, Philippines, Thailand); North America (Bermuda, U.S.A.); Central America and West Indies (Cuba, Dominican Republic, Grenada, Haiti, Jamaica, Puerto Rico, St. Vincent, Trinidad); South America (Brazil, British Guiana, Colombia, Ecuador, Venezuela). (CMI Map 258, 1952, Herb IMI and Literature) TRANSMISSION: Airborne urediospores account for the spread of the rust.

Abstract A description is provided for Cerebella andropogonis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Although Cerebella andropogonis apparently produces a disease in spikelets of grasses, it is actually a saprobe on sugary secretions of members of the ascomycete family Clavicipitaceae, and therefore by itself not a real trouble for the plants on which it grows. HOSTS: Parasitic on members of the Clavicipitaceae (Claviceps maximus, C. paspali, Claviceps sp.) growing on the following grasses: Andropogon annulatus, Andropogon sp., Anthaenantia sp., Anthisteria sp., Cenchrus sp., Cynodon sp., Dichantium annulatum, Digitaria sp., Heteropogon sp., Hyparrhenia sp., Ischaemum sp., Melinus minutiflorus, Molinia sp., Panicum maximum, P. purpurascens, Panicum sp., Paspalum plicatulum, Paspalum sp., Setaria sp., Sorghastrum sp., Sorghum sp., Spartina sp., Tricholaena sp., Trichopteryx sp. (Gramineae). GEOGRAPHICAL DISTRIBUTION: Cosmopolitan. AFRICA: Ghana [as Gold Coast], Kenya, Malawi, Mauritius, Senegal [as French West Africa], Sierra Leone, South Africa, Sudan, Tanzania, Uganda. NORTH AMERICA: USA. CENTRAL AMERICA: Cuba, Dominican Republic, Jamaica, Puerto Rico. SOUTH AMERICA: Brazil, Colombia, Paraguay, Venezuela (LANGDON, 1955). ASIA: Myanmar [as Burma], Sri Lanka, India, Philippines. AUSTRALASIA: Australia, Papua New Guinea. TRANSMISSION: By air-borne conidia.

Abstract A description is provided for Alternaria macrospora. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On cotton (Gossypium spp.) and possibly on other hosts. DISEASE: Leaf spot of cotton. On leaves a small, necrotic spot, with a purplish halo, expands to about 1 cm diam., the centre becoming grey and cracked; the zonation is more clearly defined on the upper surface. Defoliation can be severe, especially where the peduncle becomes infected (28: 65). Stem lesions begin as a small sunken spot which develops into a canker, the tissue splitting and cracking to cause a break. The glandular areas on the receptacle are also attacked and this can result in failure of the boll to develop. Flowers and bolls may be shed; the latter become mummified and the fibre attacked (20: 461; 30: 37). Boll rots can also be caused by A. gossypina (Thum.) Hopkins (17: 674; 26: 14). GEOGRAPHICAL DISTRIBUTION: Australia, Brazil, Central African Republic, Ceylon, China, Congo, Egypt, Ethiopia, Formosa, France, French Sudan, Ghana, Guadeloupe, India, Italy, Jamaica, Japan, Kenya, Malawi, Morocco, Nicaragua, Nigeria, Pakistan, Rhodesia, Rumania, Senegal, Sierra Leone, South Africa, Somalia, Sudan, Tanzania, Togo, Trinidad, Uganda, Venezuela, Zambia. TRANSMISSION: No observations appear to have been reported; seed transmission is possible.
