Botryosphaeria Ces. & De Not. 1863

This genus of ascomycetes contains several important plant pathogens like the type species Botryosphaeria dothidea. These are widespread and cause diseases like cankers, dieback, fruit rot, stem-end rot and shoot blight on woody crops. The genus is characterized by several morphological features, as well as the DNA structure of its members. E.g. the ascospores are hyaline and aseptate. However, they can become pale brown and septate with age.
