Staying over in our wood at the weekend, my son cut down a rotten silver birch. He happened to pass the spot after dark and was amazed to see the stump, the logs and all the wood chips glowing with a subtle green light. My wife and I shot over yesterday evening to see if the phenomenon was still there and witness it ourselves.
By chopping into the wood we too could get glowing. A quick bit of INTERNET research suggested wetting the wood and putting it in the warm.....which we did when we got home and it worked ! We have learnt that the glow comes from honey fungus , it is thought to be the origin of magic wands and was used by troops in the trenches to help identify friend from foe....amazing. We also found a glow worm last night near the same tree stump.
