This is a serious problem in forestry and silviculture (although not often a killer) on European Beech, Fagus sylvatica. It has been around quite some time in the UK and Europe, and it may be native to these regions. It is a fungal disease spread by a scale insect, and symptoms on Beech include the tiny white specks of the insects, weeping wounds, roughened bark, tarry spots and these jagged cankers. Generally found in woodland rather than isolated street trees. These symptoms were found by a Volunteer Tree Warden in West Kent near Tonbridge.
The disease was introduced into North America in the 1880s, where it has had quite devastating effects on the American Beech, Fagus grandifolia, and is still spreading across the North East of the continent.
