Botryosphaeria dothidea is a plant pathogen that causes the formation of cankers on a wide variety of tree and shrub species. It has been reported on several hundred plant hosts and on all continents except Antarctica.[1][2] B. dothidea was redefined in 2004, and some reports of its host range from prior to that time likely include species that have since been placed in another genus.[3] Even so, B. dothidea has since been identified on a number of woody plants—including grape, mango, olive, eucalyptus, maple, and oak, among others—and is still expected to have a broad geographical distribution.[3] While it is best known as a pathogen, the species has also been identified as an endophyte, existing in association with plant tissues on which disease symptoms were not observed.[4] It can colonize some fruits, in addition to woody tissues.[5][6][7]
