Many thanks to Kay Newbury at Reading University for the identification of this Lichen species - Parmelia sulcata.
A thallus formed of flat, "leafy", blue grey lobes 4-20cm (1.5-8in) in diameter that grows on bark, widespread and common on trees in open habitats and occasionally on rocks. Each lobe has a fine network of white lines on the surface giving it a cracked appearance. Net-marked parmelia or Shield lichen, from the family Parmeliaceae is very tolerant of pollution and is widespread making it one of the more common lichens.
