Help needed - Fungus in garden
We have a wooden border made from thick wooden sleepers around the bottom of our raised grassed area. Over the last year, a fungus has grown in one area around the bottom of the grassed area and onto the wood. It is now expanding and eating/rotting the wood.
I don't have a clue about anything like this so was wondering whether anyone can identify the fungus and tell me what I need to do to get rid of it.
