What's in a Lichen? How Scientists Got It Wrong for 150 Years


For 150 years, scientists believed lichen were defined by a symbiotic relationship between a fungus and algae. The fungus provides structure and support for the organism, while the algae produces food through photosynthesis. However, researchers recently discovered that certain lichen have an additional fungus in the mix. This threesome was revealed after a team set out to explain what made one type of lichen toxic versus another that was seemingly identical. Watch the collaborative process unfold in this short film
