Lecidea laboriosa is a species of lichen that grows inside solid rock (endolithic), with only the small black disc-like fruiting bodies (apothecia) visible above the rock surface.[2]: 301 [3] Unlike other members of the genus Lecidea, the apothecia are not lecideine in that they either lack black margins (exciples) or have gray vertically striated margins.[2]: 301  It grows all over the world in all climates.[3] It might be the most common endolithic lichen in California.[2]: 301
