This is probably caused byhoney fungus, which can kill most woody species, but normally knocks a few occasionally. Other diseases can affect individual species and the effect can be cumulative. Variegated poplar routinely suffers from poplar canker after a few years.
Nothing to do, only remove affected plants.
