Buchen-Helmling

Mycena fagetorum is a small, delicate agaric fungus in the family Mycenaceae, assessed as Near Threatened (NT). It grows on decaying beech (Fagus) litter and woody debris in mature beech woodland habitats. Its near-threatened status reflects dependence on undisturbed beech forest ecosystems that have declined through logging and land conversion.
