The fungus Septoria musiva was isolated from infected poplar plants (Populus sp.) with symptoms of leaf spot and stem canker in Paraná and Santa Catarina States, Brazil, in 2004. Pathogenicity tests and subsequent re-isolation of Septoria musiva confirmed the hypothesis that this fungus was the causal agent of the disease. This is the first report of S. musiva on poplar in Brazil.
