Script lichen
Appearance
A script lichen, or graphid lichen, is a member of a group of lichens which have spore producing structures that look like writing on the lichen body.[1] The structures are elongated and narrow apothecia called lirellae, which look like short scribbles on the thallus.[1] "Graphid" is derived from Greek for "writing". An example is Graphis mucronata.[1]
