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.

Marasmius torquescens is a small, saprotrophic agaric fungus in the family Marasmiaceae, assessed as Least Concern (LC). It produces tough, wiry-stemmed fruiting bodies that can revive after desiccation, a characteristic trait of the genus. It grows on decaying leaf litter and woody debris in woodland environments.
