Natural Dyes – Lichens: aa081499

Part 1, Part 2

Lichens are classified on the basis of their structure and can be divided into 3 major groups.

lichen

Crustose

Crustose lichens are usually found on rocks, or on wood or tree bark. The entire thallus(or body of the lichen) is attached to the substrate. When the edges of the thallus are free from the substrate, the crustose lichen is called squamulose.

Foliose

Foliose lichens are leaf-like or have distinct lobes. They are attached to the substrate by rhizines from a differentiated lower cortex.

Fruticose

Fruticose lichen are radially symmetric. The thallus is or more or less round, may be hollow or filled with white, cottony fungal hyphae. Fruticose lichen may also have a bushy structure.
