Lichen  (Opegrapha paraxanthodes)

Description

This lichen grows in a crust-like fashion; the thallus is thin and pale greenish-yellow in colour with a cracked surface (3). The Latin name of the genus Opegrapha means 'hidden writing', this refers to the long fruits, called 'lirellae', which often have a dark outer margin (4), and may resemble Chinese writing or hieroglyphs (5). In this species, however, the fruiting bodies are 'boat shaped' (2).
