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.[https://www.anbg.gov.au/lichen/what-is-lichen.html What is a lichen?, Australian National Botanical Garden] The structures are elongated and narrow apothecia called lirellae, which look like short scribbles on the thallus. "Graphid" is derived from Greek for "writing". An example is Graphis mucronata.
