Diplodia seriata, the anamorph of "Botryosphaeria" obtusa

The correct name to use for the anamorph of Botryosphaeria obtusa has been uncertain for many years. Since the genus name Botryophaeria is no longer available for this fungus the question of the correct Diplodia anamorph name must be resolved. Therefore, the aims of this work were to determine the correct name to apply to the anamorph of "B." obtusa through a study of relevant type specimens. The phylogenetic relationship of the species to its nearest relatives, and phylogenetic variation within the species were determined through a study of ITS sequence data. The species was shown to be relatively homogenous, cosmopolitan and plurivorous. The name Diplodia seriata was shown to be the oldest suitable name available. An epitype specimen is designated.
