Lichen - Xanthoria parietina
Also known as - Yellow Scale, Shore Lichen

Many thanks to Kay Newbury at Reading University for the identification of this Lichen species - Xanthoria parietina - flat, yellow conspicuous "leafy" thalli. The centre of the lichen is usually covered in disc-shaped orange fruits with a paler yellow border that gives them a jam-tart-like appearance. Occurs on bark, cement, rocky surfaces, walls and trees.

Basic species description for Lichens.

A foliose lichen with a wide distribution being listed in Australia, Africa, Asia, North America and throughout much of Europe. Typically less than 8cm (3.1in) wide. The lobes of the thallus are 1-4mm (0.04-0.16in) diameter, and flattened. Can be yellow, orange, or green-yellow, while under underneath surface is white, with a cortex, and with sparse pale rhizines0 In the past it was used as a remedy for jaundice because of its yellow color.
