Phomopsis infection kills the current year's growth on juniper branches. Stem cankers caused by Phomopsis may girdle and kill stems of numerous woody ornamentals and fruit and landscape trees. Cankers are often sunken, reddish in color with a distinct delineation between healthy and killed tissues. The fungus produces abundant fruiting structures along the killed tissue. Round, rough stem enlargements or galls may also be caused by Phomopsis .
Eggplant lesions are pale brown, sunken, with pycnidia arranged in a circle.
Black, globe-shaped pycnidia are immersed in host tissue and erupt through the epidermis. Beta conidia are single celled, clear, long and thin with a characteristic curve or bend present. Both spores should be present to confirm Phomopsis identification, but only one spore shape may be present in certain instances.
