Botryosphaeria viticola sp. nov. on grapevines: a new species with a Dothiorella anamorph

  • Author(s): Luque, J.; Martos, S.; Phillips, Alan;
  • Abstract: Botryosphaeria viticola sp. nov., isolated from pruned canes of Vitis vinifera in NE Spain, is described and illustrated. Phylogenetic analysis based on ITS and EF1-alpha sequences and morphological characters of both anamorph and teleomorph confirmed this taxon to be included within the group of Botryosphaeria species with Dothiorella anamorphs. It is related most closely to B. sarmentorum and B. iberica from which it differs in morphological characters of the teleomorph and DNA sequences.
