Q I have seen a fungus growing on the trunk of my tree. Will the tree be alright?
A Many fungi are associated with trees and what you have seen is the fruit body (flower) of the fungus which is likely to be decaying (breaking down and recycling) the wood of the tree. The effect on the tree depends on the particular species of fungus, the species of tree and the location of the fungus in the tree. Many fungi are relatively harmless or even beneficial to the tree but some cause very serious harm to the structure of the wood that can make a tree potentially hazardous.
We can identify fungi from samples (see our Disease Diagnosis service) and assess the condition of the tree by site inspection.
Please see the information on disease diagnosis.
