Cracked lichen dark

Cracked lichen dark is a tile in the Factorio system categorized as decoration; it is a decorative ground tile used to provide a dark, cracked lichen visual appearance for terrain and does not represent a functional building, recipe, or fluid. As a decorative tile, Cracked lichen dark is intended for map and aesthetic purposes to change ground visuals and is referenced by the game's tile set rather than by production or crafting systems.
