Lecidea atrobrunnea is a crustose lichen in the Lecideaceae family, found in mountains of the continental western United States and Alaska. 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. This combined lichen community appears black from a distance, but brown up close.
