L is for Lichen – Word Up!

Lichen
\ˈlɪtʃ(ə)n\
A fungus and an alga growing symbiotically (to the mutual benefit of one another) to form a pale green crinkly crust on walls, pots, trees and similar. Lichen normally appears in wetter areas where air pollution is low, and on trees whose health is already poor (although it is worth noting that lichen is not thought to cause further damage).

  1. We have loads of lichens on the trees near us, so presumably our air-quality is good!
