Lecidea atrobrunnea is a crustose lichen in the Lecideaceae family, found in mountains of the continental western United States and Alaska.[1][2][3] With other lichen communities, it forms dark vertical drip-like stripings along drainage tracks in the rock faces, resulting in Native Americans giving the name "Face of a Young Woman Stained with Tears" to Half Dome.[3]:8 It appears black from a distance, but brown up close.[3]:8
It varies greatly in its overall appearance from colony to colony.[2] L atrobrunnea subsp. atrobrunnea has been found to be common in very common in high montane zones and alpine zones.[2] L atrobrunnea subsp. saxosa ("saxosa" meaning "rock") has been found in high elevations in the San Francisco Peaks and San Bernardino Mountains.[2] The prothallus and apothecia are black, while the thallus areoles are brown. "Atro" is from Latin for "black" and "brunnea" for "brown". It was named by Ramond.[2] The upper surface is usually pale to dark reddish brown in the center of areoles. In squamulous specimens, the lower surface can be seen, and is shiny and dark.[2]
It is commonly found on rock faces in the Sierra Nevadas.[3] The communities often completely cover the exposed surface of the rock, or form intricate multicolored mosaics with other lichen communities.[3]:8 It's communities are park of the aesthetic appeal to visitors of Yosemite National Park and Sequoia National Park.[3]:8
It is found in the Rocky Mountains, including in alpine zones, and in the United States Sierra Nevada range.[1][3] Lichens in relation to management issues in the Sierra Nevada national parks, McCune, B., J.
