Paleobotanist Az Klymiuk didn’t set out to upend science’s understanding of the fossil record of plant-fungal associations. She just wanted to figure out the environment that some fossil plants lived in. That question led her to look at modern cattail roots and the fungi that live inside of them. She found that fungi have a harder time growing in cattail roots that are underwater. And that discovery, which is being published in the journal Mycologia, could change how we interpret some parts of the fossil record, including an important community of early land plants.
