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.

Gras-Stromabecherling

Rutstroemia calopus is a discomycete fungus in the family Rutstroemiaceae, producing small, stalked, cup-shaped fruiting bodies on decaying plant material. It is saprotrophic, decomposing dead stems and woody debris in moist habitats. Its conservation status is not evaluated.
