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.

Torodinium robustum is a marine dinoflagellate characterized by its robust, elongated cell body with distinctive spiral grooves. It inhabits coastal and open ocean waters worldwide, particularly in temperate and tropical seas. As a photosynthetic protist, it produces energy through photosynthesis while also consuming dissolved organic matter.
