Show notes

When you see a mushroom popping up from the forest floor, that mushroom is just the tip of the fungal iceberg for a vast world beneath the surface. But the nature of fungal life makes it hard to answer some basic questions. What exactly does it mean to be one individual organism? And how do you tell how old a fungus is, when parts of it can recycle, regenerate, and grow again? Flora talks with fungal researcher Kristin Aleklett about the [https://www.sciencefriday.com/segments/age-of-a-fungus/?utm\_source=wnyc&utm\_medium=podcast&utm\_campaign=scifri"]( challenge of fungal age, and how researchers are trying to better understand what fungi are doing in the world under the ground. Guest: Dr. Kristin Aleklett is a researcher at Lund University in Sweden. _Transcript will be available after the show airs on_ [https://www.sciencefriday.com/segments/age-of-a-fungus/?utm\_source=wnyc&utm\_medium=podcast&utm\_campaign=scifri"]( _sciencefriday.com._ [https://pod.link/73329284"]( _Subscribe to this podcast._ _Follow our show on_ [https://www.instagram.com/scifri/"]( _Instagram_ _,_ [https://www.tiktok.com/@scifri"]( _TikTok_ _,_ [https://www.facebook.com/scifri"]( _Facebook_ _, and_ [https://bsky.app/profile/scifri.bsky.social"]( _Bluesky_ _@scifri and_ [https://www.sciencefriday.com/newsletters/?utm\_source=wnyc&utm\_medium=podcast&utm\_campaign=scifri"]( _sign up for our newsletters_ _.
