Moss on a wall

Day 4 of the Cotswolds way.
Better than yesterday which is not hard. 
It didn't rain and in fact the sun came out later on this afternoon:-). It was slightly less muddy and definitely shorter, 11 miles today from Charlton Kings to Birdlip. 
As we were walking up one of the hills I noticed this moss and thought it would make a different sort of blip!
