From the field to the lab, we take a brief look at how lichens are identified by sight and by chemical spot tests. This video was made for a Lichenology class at Oregon State University by Jena Fay and Sara Lynch. Lichens mentioned here include Cladonia, Lobaria, Evernia, Usnea, Ramalina, Xanthoria and Bryoria. Happy identifying!

Thank you! I have so much lichen where I live (just outside of Yosemite National Park). I just started to learn about it because it is so cool looking and it is everywhere up here. After watching this I am going to learn more about it than just the names.

@luciachmurova3008 5 лет назад

hello, you didn't really explain why the spot test is helpful, is it for species identification?

@rachidmouedden5725 5 лет назад

Hi lts réély very interesting thanks

@mralsop7342 7 лет назад

Hi Sara could you tell me if the book macrolichens of the northwest tells you in any detail on how to check lichens through a microscope or how to identify by using chemicals or maybe you could point me in the right direction to such a book I am just getting into lichens and can find nothing but books with pics for identifying and I cant seem to identify for sure by pics alone that may just be me though

@saralynch391 7 лет назад

It’s an excellent book and key. The pictures are all closeup, but none are under the microscope. However, there is LOTS of information about chemical tests for identification in here. The author was my university professor, Bruce McCune, with Linda Geiser. I don’t know where you are, but Macrolichens of the Pacific Northwest might be at your library, and it’s on Amazon: smile.amazon.com/Macrolichens-Pacific-Northwest-Second-Ed/dp/0870715658/ref=sr_1_1?ie=UTF8&qid=1487881625&sr=8-1&keywords=macrolichens+of+the+pacific+northwest. It is worth its weight in gold.

@mralsop7342 7 лет назад

Thanks for your reply sara, im actually near London England I'm guessing we share the same lichens over here and id like an array of lichen books so I ll check it out thanks again.

@Dovid2000 7 лет назад

Are there lichens that are naturally fragrant, with a pleasant scent?

@saralynch391 7 лет назад

I don’t know of any off hand, but I do know that some lichens contain a chemical that is used for balancing fragrance in perfumes, if that helps!

@Dovid2000 7 лет назад

Thanks for your reply, Sarah.

@michaeltyler7166 6 месяцев назад

around 5:13 your stating that maritime sunburst lichen is called santeria, is there a reason i dont know and when googling just simple santeria its a green shrub smoked in africa simular to marjuana or tobacco, but when looking up Maritime Sunburst Lichen you will see exactly what your showing.

@saralynch391 6 месяцев назад

The genus for this lichen is Xanthoria.

@charlesgardner4219 9 лет назад

What is the source for KOH and P test crystals?

@saralynch391 8 лет назад

+Charles Gardner Sorry for the late reply. We had access to these chemicals at Oregon State University, and I understand that if you work in a lab they can be acquired more easily. I have been told that if you contact a society such as Northwest Lichenologists they can help you find information on how to order lab chemicals as well. Good luck!

@charlesgardner4219 8 лет назад

thanks, I think I will be able to use my affiliation with BRIT (Botanical Research Institute of Texas). They indicated we mightt do it next week. Got the KOH through Amazon of all places...

After watching this I'm really lichen lichens LOL

@ZomBeeNature 6 лет назад

You seem to mix everything together from one sample to the next, and the ceramic thing doesn't look clean, and the chemicals too, and bare fingers on the paper... It seems like you would cross-contaminate everything and not really know what you had... 😢

@saralynch391 6 лет назад

I understand why you might think that, but these are pretty simple identification tests that don’t require sterilization; you can just use a wet cloth to wipe out the wells between tests. Keep in mind this is a university classroom with older equipment and things get stained over time!
