Fungus

We have a fungus growing (and expanding) in our lawn. I dig it up, it returns. I've put down lawn sand but its still there. The lawn is about 18 months old, it was laid by a firm and is Sovereign turf.

here's the pictures ...

also - one of my trees has died - so says the local tree surgeon with honey fungus disease - it was an apple tree that was pruned last Feb and had been doing well. Some of the bark is coming off and there was a fungus growing at one side of the base. Does it have to come down - is there anything we can try as its a tree with a lot of memories for us.

Thanks
