Mystery crusty lichen

This morning I went to the dentist to have a lost filling replaced then afterwards called in to say hello to F who was busy bricklaying.  Luckily for him the rain had stopped.

I went to Ifton Meadows for a walk round.  Mine was the only car in the car park and I didn't see anyone else so a quiet walk!  The only birds that I saw were chaffinches but there were a number of different types of fungi.

This pink crusty lichen was very pretty and growing on a tree trunk.  I've looked in my books and online but have failed to identify it.  Perhaps one of you will know.

My extra photo is of some grass covered in raindrops which looked beautiful.
