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.[1][2] Stigmidium microspilum and Arthonia graphidicola are associated lichenicolous fungi.[2] 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.[2]
