Lecture 23 Fungi Review life cycles Ascomycota and Basidiomycota Fungal symbionts • Parasites o Plants o Exotic plant pathogens o Animals o Chytridiomycosis o White Nose of bats o fungi • Mutualists: o lichens o mycorrhizae o endophytes o animals • Example: Lichens • Symbiosis: fungi with green algae and/or cyanobacteria • Fungi: ~20,000 species known to form lichens o Most are obligate • Photobiont:~100 species of green algae and cyanobacteria are known to form lichens o 85% lichens associated with green algae o 10% lichens associated with cyanobacteria o 5% lichens associated with both green algae and cyanobacteria • Fungus makes up the bulk of the lichen thallus (body) • Fungus receives carbon from the photobiont; may receive nitrogen if cyanobacteria are involved. • It is unclear what benefit the photobiont receives: possibly mineral nutrients, water or protection from the environment • Nearly all lichen forming fungi are obligately dependent on their photobiont; i.e., they are not free-living
