Document Summary

Elk death in the red rim-daley wildlife habitat management area. The result of a relationship between a fungi and one or more photosynthetic partners. A species is a genetically unique organism that can reproduce successfully. Lichens don"t really combine to reproduce completely, but we still simplify it . Lichens are named by their fungal component, because that"s really the only way to identify them. Cladonia rangiferina + trebouxia irregularis = cladonia rangiferina. Cover about 8% of the terrestrial surface of the planet. Some lichens grow at a pace of 0. 5-3. 0mm per century! The fastest growing lichen on record grows at a rate of 2. 0mm per 12 years. 20% of fungal species are of lichenized fungi. Lichens can be naturally found on every continent, often in the harshest environments. The two types of organisms that make up the thallus, or body, of the lichen: One of the most successful organisms on the planet.
