Botryosphaeria spp. are common endophytes and latent pathogens of woody hosts causing a wide range of symptoms such as shoot blights, cankers and fruit rot. The taxonomy of this genus has been confused due to the similarity of the teleomorph and overlapping characteristics of the anamorphs. Recently DNA sequence data has been used successfully in conjunction with morphological characteristics to resolve taxonomic questions. ill particular cryptic species such as B. ribis and B. parva, which have overlapping morphological characteristics, have been clearly separated based upon sequence data. However, we now have a number of isolates from eucalypts in Australia that do not fall neatly into either B. ribis or B. parva suggesting either a species complex or a complex of species. Various scenarios for these isolates were tested the morphological, biological and phylogenetic species concepts.
