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 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.
