Acarospora elevata, the mountain cobblestone lichen, is a shiny dark reddish brown to dark brown verrucose to aereolate crustose lichen that grows up to 3 cm (1.2 in) wide on granite in central and southern California to Baja California, and high elevations in the Rocky Mountains.^[1]^{: 216–217}^[2] It is usually only found above 1,400 metres (4,600 ft) because it is eaten by red mites at lower elevations.^[1]^{: 216–217}^[2] In the Californias, it is mostly found at high elevations (hence "elevata"), but sometimes in coastal locations where it is less glossy.^[2] It grows in full sun, mostly on hard granite, but sometimes other igneous or carbonate rock, from 500 to 3,350 metres (1,640 to 10,990 ft) in elevation.^[2] It may start by growing on members of the genus Aspicilia, or other such pioneer species on hard rocks.^[2]

There are typically between zero and four apothecia on each areola or wart, with dark red or black, rough surfaced, flat to concave discs without a dusty looking surface pruina.^[2] The asci are thicker at the top than at the base (clavate).^[2]

Lichen spot test are all negative, and it is UV- under ultraviolet light.^[2] It may be identical with type of .^[2] The lower-elevation forms were originally called and .^[2]

Acarospora is in the family Acarosporaceae. A. elevata was first described scientifically by lichenologist Adolf Hugo Magnusson in 1929.^[3]
