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.

Sphacelaria tribuloides is a small, tufted brown alga forming compact cushion-like colonies on rocky substrates and larger algae. It inhabits intertidal and shallow subtidal rocky zones in temperate and tropical seas worldwide. This photosynthetic alga reproduces via characteristic star-shaped propagules and colonizes rocky marine surfaces.
