Acarospora schleicheri, the soil paint lichen, is a bleached to bright yellow areolate to squamulose lichen that commonly grows to 10 cm (4 in) on soil ( terricolous) in arid habitats of southern California and Baja California, also in Europe and Africa. [2]: 218 [3] It produces rhizocarpic acid as a secondary metabolite, [3] which gives it a yellow coloration and serves to protect it from the sun. [4] Its lower surface is also yellow. [3] It can be greenish when moist. [2] Roundish, angular, or irregularly shaped squamules are 0.5–4 mm in diameter. [3] There are 0–1 (sometimes 2–3) apothecia embedded in the thallus, with 0.4–1.2 mm roundish black to reddish-brown, [3] or dark brown [2] discs, which sometimes fill the areola so as to be lecanorine. [3] It divides vegetatively on the soil. [3] Asci are club shaped (clavate) and have 100 or more spherical to ellipsoid spores. [3] Lichen spot tests are negative, and it is UV+ orange under ultraviolet light. [2]: 218
