Resumo: The Alternaria alternata has been already isolated from potato leaves, in Brazil, however, the occurrence of this fungus on potato tuber has never been reported. This study aimed at confirming the occurrence of A. Alternata in lesions present in potato tubers. Thus, lesions on the diseased tubers were examined in a stereomicroscope, in order to prepare semipermanent microscope slides by removing the mycelium and fungal structures found on the infected tuber tissue. The conidia presented the shape of an inverted pear, light brown, with dimensions of 19.7-45.4 x 8.5-18.6 ?m (28.3 x 12.5 ?m), and 2-6 (4) transversal and 1-5 (2) longitudinal septa, while the conidia beaks measures were 2.6-11.9 ?m (4.4 ?m). These features characterized the fungus as A. alternata.

Este trabalho objetivou confirmar a ocorrência de A. alternata em lesões presentes em tubérculos de batata. Para tanto, as lesões dos tubérculos atacados foram examinadas em estereomicroscópio, para a confecção de lâminas microscópicas semipermanentes, mediante a remoção de micélio e estruturas fúngicas encontradas sobre o tecido vegetal infectado. Os conídios apresentaram dimensões de 19,7-45,4 x 8,5-18,6 ?m (28,3 x 12,5 ?m) e formato de pera invertida, com coloração marrom clara e 2-6 (4) septos transversais e 1-5 (2) longitudinais, e as dimensões dos bicos dos conídios foram de 2,6-11,9 ?m (4,4 ?m).
