Fusarium culmorum, F. moniliforme, F. equiseti, and F. semitectum were found infecting rice (Oryza sativa) in Las Marismas (Sevilla) in 1977 and 1978. These species differed in distribution, incidence of infections, and symptomatology induced in affected rice plants, with F. moniliforme being the most important. As far as we know, this is the first report of F. equiseti and F. semitectum as pathogens of rice. F. semitectum was isolated from necrotic lesions in evolving sheaths of panicles and glumes and from vascular tissues of culms showing brown discoloration. F. equiseti was isolated from adult plants showing a discoloration in vascular tissues of the culm.
