Whilst walking long the Bewdley quayside in Severn Side South Ann Hill photographed this moss. In the hot weather it was drying out, but mosses soon revive when they are moistened by the next rain and this allows them to survive in dry situations. This species is commonly found on rocks and tree bark as well as man-made structures, especially where the substrate is base-rich.
