Chemotaxonomic Studies on Some Stereocaulon (Stereocaulaceae, Lichenized Ascomycota) from Southern South America and Antarctica

Orbital: The Electronic Journal of Chemistry
Lichenized fungi (lichens) produce many compounds especially those derived from the polyketide pathway. These are predominantly phenolic compounds, most of which are unique to lichens, and long-chain fatty acids.
