Acarospora thelococcoides

Species of lichen

Acarospora thelococcoides is a pruinose (dusty whitish) verruculose (warty) crustose lichen that grows in patches up to 10 cm across that grows on soil (terricolous), especially soils made from decomposed granite.[1]: 220 [2] It grows from San Benito, California to Baja California, and inland to 930 metres (3,050 ft).[2] Each roundish areole becomes more pruinose toward the top and typically has a single round apothecium that is immersed with a dark brown disc, so as to appear like a collection of white rings.[2] This appearance gives it the common name, soil eyes lichen.[1]: 220
