Lichens are a symbiosis (two or more organisms living together more successfully than they could on their own). The basic components of lichens are a fungus called the 'mycobiont' and one or more algae and/or a cyanobacteria called the 'photobiont'.
The following links and references will be useful to anyone interested in lichens. Australian references are provided since New Zealand shares many lichen species with Australia:
