INTRODUCTION:
Lichens are symbiotic organisms formed by a partnership between a fungus and an alga or cyanobacterium. They are commonly found on rocks, trees, and soil, especially in dry and harsh environments. Lichens can survive extreme conditions and play a vital role in ecosystems by aiding soil formation and indicating air quality.
