Honey Fungus

Honey fungus can be a major killer in woodland gardens. Black 'bootlaces' spread just underground from rotting stumps and may go over 10m.

Some forms of this fungus are harmless but other, seemingly identical, forms will grow into the roots and stems of a variety of trees and shrubs, often killing them.

There is no really effective remedy; the important thing is to remove or stump-grind all tree stumps and plants suspected of dying from this fungus.
