Abstract

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).
