Mycena epipterygia, the yellowleg bonnet, is a species of fungus in the family
Mycenaceae, native to Europe. It grows on the floor of deciduous and coniferous woodland as well as on acid grassland, and among mosses, as seen here at
Erbach an der Donau, in
Baden-Württemberg, Germany. The sticky, bell-shaped cap becomes more convex with age, and varies in colour, the slender cylindrical stem being yellowish-green, which helps to distinguish this fungus from other species. Some parts of the fungus, including the
mycelium, are
bioluminescent.
