Can anyone suggest what might be killing this cotoneaster?
Is the white stuff lichen and if so is it cause or effect?
The whole plant is going at once rather than a branch at a
time but the ones either side appear to be okay - so far!

Sorry, but it is a reasonable size file in order to keep the detail.
