Honey fungus

Honey fungus is the common name given to several different species of the fungus Armillaria that attack and kill the roots of many woody and perennial plants. The most characteristic symptom of honey fungus is white fungal growth between the bark and wood, usually at ground level. Clumps of honey-coloured mushrooms sometimes appear briefly on infected stumps in autumn.
