Answer:

This is because body of lichen is that of Thallus.

Explanation:

There are mainly three types of thalli classified in Lichens:

1. Crustose lichens
2. Foliose lichens
3. Fructicose lichens

The Crustose lichens are those lichens which lie on the rocks and barks. The Foliose lichens are more like lobe leaf structured and they grow more or less like substratum. Fructicose lichens have a structure much more branched as compared to the Crustose and Foliose lichens.

Lichens are important for environment and play a major role in soil formation. The Crustose lichens, which grow on rocks, dissolve the rocks and make them break into smaller pieces, thus forming soil.
