Identification of Botryosphaeria anamorphs associated to grapevine in Brazil.

Several species of Botryosphaeríaceae have been isolated frequently from grapevines showing decline, dieback symptoms and brown-wood streaking. A major problem of the grape and wine industry concerns the correct identification of the Botryosphaeríaceae species causing disease on vines since the diversity of anamorph in this family leads to some taxonomic difficulties. In this study, 42 isolates of anamorphic Botryosphaeríaceae associated with grapevines were found in four states of the South and Southeast of Brazil, and were distinguished after their anamorph characteristics such as colony and conidial morphology.Resumo P.
