Lichens You're Gonna Be "Lichen" It!
Meet the Lichen Group Forensic Traitor (Whitney) William Melanie Virginia Tristan Joni Annie
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
This is NOT a Lichen • Has a flowering reproductive system
Nor is THIS a Lichen • This is a bromilliad (from the pineapple family, which grows on trees )
This is a Moss with Liverworts • (Not lichens either)
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
Where do Lichens Grow? • Trees • Rocks • Metal • Dirt • Dr. Bauman • The Backs of Beetles
Ramalina celastri • Fruticose
Teloschistes exilis • Fruticose
Buellia spuria • Crustose
Usnea cirrosa (Dr. Seuss Plant ) • Fruticose
Paromotrema hypotropum • Foliose

Continued Study of Formerly Plotted Areas • Number of lichens on plot near stream -379 different colonies • Number of lichens on plot near road - 528 different colonies • Number of lichens on plot on tornado blown hill - 131 different colonies
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
What Are Lichens Good For? • Bio-indicator (helps tell where pollution is present) • Bird nest material • Recharging the soil with nitrogen • Food for animals such as reindeer and ticks. • Help break down rocks and dead trees • Medicines, dyes, and clothing materials
“To find them in abundance is to find a corner of the universe where the environment is still pure and unspoiled,” Lichens of North America
