Lichen is found growing on trees and elsewhere in the garden or forest. It is a symbiotic fungus/alga characterised by flat topped organisms. Lichenoid skin disorders got their name from their appearance – also flat topped and often somewhat scaly. They are characterised by a particular type of inflammation found on histology.
