i just read on this and first make sure its not in line with your car starting because it could be car smoke, sounds daft but can happen, if not it can be caused by sap sucking insects from plants near by or above aphids secrete honey dew basically a sugary substance and black mould grows on this
or if powery mildew spray milk on this, thats all i could come up with , hope it helps
