  3. What is a Lichen? • A symbiotic relationship (where two species help each other live) between a fungus and photobiont Algal cell Provides sugar (food) Fungus Provides stability and structure

  4. This is NOT a Lichen • Has a flowering reproductive system

  5. Nor is THIS a Lichen • This is a bromilliad (from the pineapple family, which grows on trees )

  6. This is a Moss with Liverworts • (Not lichens either)

  7. Three Basic Types 1. Fruticose A long strand erect or hanging from the substrate 2. Crustose A lichen impossible to remove from the substrate 3. Foliose Leaflike and easy to remove from the substrate

  8. Where do Lichens Grow? • Trees • Rocks • Metal • Dirt • Dr. Bauman • The Backs of Beetles

  9. Ramalina celastri • Fruticose

  10. Teloschistes exilis • Fruticose

  11. Buellia spuria • Crustose

  12. Usnea cirrosa (Dr. Seuss Plant ) • Fruticose

  13. Parmotrema austrosinese

  14. Paromotrema hypotropum • Foliose

  23. What Kills a Lichen? • Lichens cannot flourish near polluted areas such as near houses or roads • Many lichens cannot live out of the shade • Lichens cannot live in flooded areas • Wood chippers kill lichen
