Entoloma bryorum is an agaric fungus in the family Entolomataceae, growing in association with mosses (bryophytes) in humid, undisturbed habitats. Like other members of the diverse genus Entoloma, it produces pink spores and may have saprotrophic or mycorrhizal associations. Its conservation status is not evaluated.

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.
