When we were trimming the beech hedge in our garden this year we found a few dead branches that just snapped off, initially not alarmed, I then followed the dead branches and realised that actually it was one whole bush/tree/plant (what do you call the individual plants in a hedge?) that was dead. It has a whiteish pink fungus all over it. I separated these branches from the rest, thinking I wouldn't shred them, I would burn them, but then thought perhaps we should try to find out what it is. I have just gone outside to get a couple of the branches to photograph, and there is now a lot less of the stuff on the branches I separated, some of them have no visible signs left at all. They have been lying on the lawn for 7 days. Does anyone know what this is?
