trunk Lichen
Lichens may be flat, leafy, crusty, powdery, or hair-like. They occur on tree bark as well as on rocks, soil, fence posts, etc. Colors may range from white to gray, red, green, yellow, or black. The presence of some lichens is normal on many trees and shrubs.
Epiphytes attach themselves to plants, but they do not harm the plants. While epiphytes may grow on wires, fences and other non-living structures, they are particularly well-adapted to grow on woody plants in well-lit, moist and humid habitats, especially near rivers, ponds and lakes.
