These fascinating organisms are a unique symbiotic partnership between fungi and algae or cyanobacteria. There are three different types, all seen in this image.

Crustose Lichens: These lichens form a tightly adhering crust-like layer on the substrate such as rocks or bark. They are often found in harsh environments like deserts and high-altitude regions.

Foliose Lichens: Foliose lichens have leaf-like structures and are typically loosely attached to the substrate. They can be found on trees, branches, and soil and are often more sensitive to environmental changes.

Fruticose Lichens: Fruticose lichens have a branching or bushy structure and may be upright or hanging from substrates. They are often found in various habitats, including forests, tundras, and coastal areas.

Lichens can be found almost everywhere, from the Arctic tundra to tropical rainforests and even on bare rock surfaces! Their ability to thrive in diverse environments makes them excellent indicators of air quality and environmental health.

Fun fact: Lichens are pioneers in ecological succession, breaking down rocks and paving the way for soil formation, which allows other plants to grow.
