Lichen is the result of an alliance between two very different types of organisms, a fungus (or more than one) and a single celled alga. The consequence of this association is the production of beautiful, natural forms that can clothe surfaces such as rocks, soil or plants with strongly sculptural and interesting shapes and colours.
In the lichen symbiosis the fungal partner provides structure and sexual reproduction while the alga provides food through photosynthesis and sometimes nitrogen fixation. In New Zealand we are fortunate to have one of the richest lichen floras in the world, with around 1000 described species in over 200 genera.
My love for the beauty of lichens comes from years of observing them in the New Zealand environment as I have wandered with my backpack, sketch book and camera along river beds, up hillsides to the bush edge and into our alpine environments.
