Graphis scripta is a crustose lichen in the family Graphidaceae. It is commonly called script lichen, secret writing lichen, or similar names, because its growth pattern makes it looks like writing.[https://books.google.com/books?id=YM0wAQAAMAAJ&dq=Graphis+scripta+secret+writing&pg=PA216 The Deeper Teachings of Plant Life, Hugh Macmillan][http://www.dorsetnature.co.uk/pages-lichen/lch-99.html Graphis scripta, Holton Lee, October 2012, Dorset Nature] Stigmidium microspilum and Arthonia graphidicola are associated lichenicolous fungi. It is variable with either curved or stellate apothecia. The margins are carbonaceous and raised, without furrows. Mature spores are without color, but become brown with age.
