Sumpfdotterblumen-Becherling

Botryotinia calthae is an ascomycete fungus in the family Sclerotiniaceae, the sexual stage of a Botrytis-like pathogen that infects marsh marigold (Caltha palustris) in wetland habitats. It forms sclerotia in infected plant tissue that persist in soil to initiate future infections. As a necrotrophic pathogen, it kills host tissue and then feeds on the resulting dead material.

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.
