Bellemerea alpina (brown sunken disk lichen) is a white to pale tan, thick crustose areolate lichen that grows on rock in the mountains worldwide.[1] It grows in arctic-alpine habitats in Eurasia, North America (south to California and Arizona), Australia, and New Zealand.[1][2]: 228 Areoles are sometimes contiguous and sometimes dispersed.[2]: 228 It often has very visible black prothallus.[2]: 228 The brown to tan apothecia have a purplish tinge and are grayed by a pruinose coating, and embedded in the areoles, giving a similar appearance to members of the genus Aspicilia.[2]: 228 [1]
