Several of us on here have honey fungus in our gardens, ERB, and have to live with it.
The RHS lists are very useful. My advice is to dig out as much root as possible from those things which have been killed and certainly never leave stumps as these serve as a home-base for HF. Regular cultivation of the soil in affected areas seems to help too as this breaks the rhizomes which is how HF spreads to other trees and shrubs.

Good luck and don't despair!
