Acarospora contigua is a species of saxicolous (rock-dwelling), crustose lichen in the family Acarosporaceae.[1] It was formally described as a new species in 1929 by Swedish lichenologist Adolf Hugo Magnusson.[2] The dark yellow thallus has a continuous smooth crust comprising areoles that are 1–2.5 mm in diameter. In North America, it is known as the gold cobblestone lichen.[3] The lichen was reported from the Eastern Ghats India in 2021, where it occurs in tropical conditions at elevations between 500 and 1,000 m (1,600 and 3,300 ft).[4]
