Script lichen

Graphis scripta


Graphis scripta is a crustose lichen in the Graphidaceae family. 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.-Wikipedia


Spotted at the base of a large cottonwood tree that is located in a wetland habitat.


The area on the tree that this lichen covered is about 1.5 ft wide and 3.0 ft.tall.
