  8. Pictures • White Truffle

  9. Pictures • Redwood seedlings with, right, and without, left, mycorrhizae

  10. Importance of Lichen and Mycorrhizae • They provide a place for algae to survive in harsh conditions (lichen) • They absorb anything in the air, especially pollutants (lichen) • Provide nutrients for host plants by increasing the rate of decomposition in the root area of the plant (mycorrhizae)

  11. Life cycle http://kentsimmons.uwinnipeg.ca/16cm05/16labman05/lb2pg20_files/image004.jpg

  12. Interesting Facts • Lichens are many times the first organism to settle in an area with no soil • It is estimated that lichens cover 8% of the earth • Some Lichens may be over 10,00 years old, in the Antarctic • Some mycorrhizae can protect roots from other fungus http://itotd.com/articles/637/lichens/
