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

It is similar in appearance to Catillaria lenticularis, Polyspora simplex, and Sarcogyne clavus.[2]:301

It is negative to lichen spot tests, K-, P-, C-.[2]:301[3]
