• Poor or stunted growth
• Yellowing or wilting leaves
• Branch and crown dieback
• Declining tree health
• White fungal growth beneath the bark or around the roots
• Honey-coloured mushrooms, usually appearing in autumn

Honey Fungus can spread from infected roots or stumps to nearby susceptible plants.

Removing an infected tree stump and as much accessible root material as practical can help reduce potential sources of infection, although stump removal alone cannot guarantee that Honey Fungus will be eliminated from the soil.
