Description
Bruise lichen is a group of lichens often found on soil, rocks, or bark in arid regions. They form small, dark-colored, scaly or granular structures on their substrate. Some species in this group have a unique bluish-gray coloration. Bruise lichen lichens play a crucial role in stabilizing soil in desert ecosystems and are indicators of air quality in certain environments.
