Dimelaena oreina, the golden moonglow lichen, is a greenish yellow placodioid lichen.[3] The color of the greenish yellow thallus is derived from usnic acid in the cortex.[3]

Habitat and range

[edit]

The lichen grows on steep surfaces of hard siliceous rock from 400 to 2,800 metres (1,300 to 9,200 ft).[3] It has a worldwide distribution outside the tropics, Australasia, and Antarctica.[3] It is common in the Sonoran Desert of Arizona, California, Baja California, Baja California Sur, Sonora, Mexico, and Chihuahua, Mexico.[3]

In Nepal, Dimelaena oreina has been reported from 3,200 to 4,884 m elevation in a compilation of published records; this reported range extends above the tree line used in the study.[4]
