Quick Summary

Trebouxia is a genus of green algae that is commonly found as a symbiotic partner in lichens. These algae are characterized by their branching filaments and lack of hairs, and they can grow both prostrate and upright. While Trebouxia species are known to be a significant component of many lichens, free-living populations of this genus have not been discovered. The algae are typically reddish or orange-tinted and grow on rocks and tree trunks. They are a type of green algae, which, according to cladistic analysis, should be grouped with land plants.12345
