Other equally fascinating instances of niutualistic symbiosis in- volving two plant species are to be found in nature. A well-known example, and one already mentioned as of great ecological importance in relation to nutrients (Chapter 8), is the bacteria of the genus Mature lichen Ascospores. Pure cultures Fungus Clasping hyphae^- Association Lichen is formed in nature but rarely in laboratory Fig. Diagram illustrating the symbiotic partnership represented by the lichen Cladonia cristatella and its separation in the laboratory into algal and fungal components. When the components are recombined in the laboratory, the typical morphology of the lichen is not developed, evidently because of the lack of certain environmental conditions found in nature.
