Lichens A perfect marriage of algae and fungi
Take a closer look at the yellow patches on walls, trees, and stones – those are lichens! This unique collaboration between fungi, yeast, and algae forms an ecosystem of its own. In the Netherlands alone, over 650 species of lichens can be found, though sadly, half of them are threatened.
How do lichens survive?
Lichens thrive in places where plants often cannot, such as stones or in extreme cold. Their clever symbiosis makes this possible. The fungus provides protection, the algae produce food via photosynthesis, and the yeast helps with defence mechanisms.
Remarkable species of lichens
Lichens come in many shapes and colours, from the powderhorn lichen (Cladonia humilis) to the vibrant devil's matchstick (Cladonia floerkeana). Some species, like reindeer lichen, even serve as a vital food source for animals in harsh environments.
Lichens and air quality
Did you know lichens are used to measure air pollution? These microbes are extremely sensitive to harmful substances and were once the sole method for monitoring air quality.
