What is Lichen?

There are around 20,000-30,000 species of Lichen Worldwide. Lichen is made up of two or more organisms working together, one of which is a type of fungi. It is thought Lichens are the first example of fungi and can be found growing on bark and rocks where they absorb water and essential nutrients from the environment around them. You would most likely find these on very old trees and ancient woodlands as Lichen is extremely slow growing and these undisturbed trees and woodland would give Lichens a place to safely grow for years to come.

The three main types of Lichen

Crustose having a flat shallow crusty appearance.

Foliose which has a raised edge and leafy appearance.

Fruitcose which is more shrub like or wispy.
