Fly Agaric

El matamoscas (Amanita muscaria) es uno de los hongos más icónicos y reconocibles de la Tierra, con llamativos sombreros rojos con manchas blancas en los bosques boreales del hemisferio norte. A pesar de su apariencia de cuento de hadas, contiene potentes compuestos psicoactivos como muscimol y ácido iboténico y es moderadamente tóxico. Forma simbiosis micorrícicas esenciales con abedules, pinos y abetos, intercambiando nutrientes minerales por carbono y desempeñando roles fundamentales en el ciclo de nutrientes de los bosques boreales.
