Spore Sized: Ice Age Mushrooms: How Ancient Fungi Survived in Alaska's Hidden Refugium

Discover the genetic secrets of Alaska's ancient fungi and how these incredible Ice Age mushrooms survived the brutal Pleistocene epoch. If you are fascinated by Beringian relics and the hidden biology of the far north, this deep dive explores the microscopic shadow kingdom operating right beneath our feet.In this episode, we unpack the cryptic diversity of the iconic Amanita muscaria, analyzing how fungal DNA reveals multiple isolated lineages that survived the Last Glacial Maximum. We also explore the discovery of new crustose lichens in Katmai National Park, the fascinating symbiosis of ectomycorrhizal fungi, and the booming ecology of post-wildfire morel harvesting. Finally, we discuss the deadly toxicity of false morels and how climate change is fundamentally rewiring the Arctic tundra.Grab your field guide and join us as we explore the resilient, ancient, and sometimes deadly world of Alaskan mycology!
