Explanation:
Lichens are symbiotic associations of mutualism between fungi and algae. Most lichen-forming fungi are ascomycetes (98%), the remainder being basidiomycetes. The algae involved in this association are chlorophytes and cyanobacteria. The fungi of this association are called mycobionte and the algae, photobionte, since it is the photosynthetic organism of the association.
The dual nature of lichen is easily demonstrated by the separate cultivation of its components. In the association, the fungi take different forms from those they had when isolated, most of the body of the lichen is formed by the fungus.
