Fungus on driftwood

I know this is'nt strictly trees but it is an old branch! I have some driftwood which I have a a garden sculpture. It has grown tan coloured mushroom like fungus. Is this harmful? Will the spores infect other plants? Will it go when it gets warmer? Shouldn I throw it, spray it with anti fungicide or what. All help appreciated.

 

Most fungi infecting dead wood will not attack live plants or trees. To help prevent further rotting of the wood you could give it a good drench with Amillatox and then apply some clear wood preservative when it has dried.

 

I agree with frogesque, I believe, (I may be wrong but) most fungi will only affect other trees and shrubs if they are wounded and the spores can get in. Fungi can be a very attractive feature and encourage some beneficial insects. Unless It's honey fungus. In which case, If possible, i'd soak either end of your branch in a bucket of solution of armillatox (If too big for a bucket, paint on some armillatox neat and leave to dry. re-apply a couple of times.) Scrub the branch with the same solution. All this after removing the fungi fruits.
