Fly Agaric

Among the most iconic and recognizable fungi on Earth, fly agaric mushrooms display striking red caps with white flecked warts across boreal forests of the Northern Hemisphere. Despite their fairy-tale appearance, they contain potent psychoactive compounds including muscimol and ibotenic acid and are moderately toxic. They form critical mycorrhizal symbioses with birch, pine, and spruce trees, exchanging mineral nutrients for carbon and playing essential roles in boreal forest nutrient cycling.

Lactarius flavidus is a gilled mushroom in the milk cap genus with a pale yellowish cap and white to yellowish latex that exudes when cut. It grows in Mediterranean and southern European forests, forming ectomycorrhizal associations with oak and pine trees. This fungus exchanges soil nutrients for photosynthetic sugars with its tree partners.
