Mycena aurantiomarginata
Mycena aurantiomarginata, commonly known as the golden-edge bonnet, is a species of agaric fungus in the family Mycenaceae. The mushrooms have a bell-shaped to conical cap up to 2 cm in diameter, set atop a slender stipe up to 6 cm long with yellow to orange hairs at the base. The fungus is named after its characteristic bright orange gill edges.
About Mycena aurantiomarginata in brief
Mycena aurantiomarginata, commonly known as the golden-edge bonnet, is a species of agaric fungus in the family Mycenaceae. The mushrooms have a bell-shaped to conical cap up to 2 cm in diameter, set atop a slender stipe up to 6 cm long with yellow to orange hairs at the base. The fungus is named after its characteristic bright orange gill edges. A 2010 publication reported the discovery and characterization of a novel pigment named mycenaaurin A, isolated from the mushroom. The pigment is responsible for its color, and it has antibiotic activity that may function to prevent certain bacteria from growing on the mushrooms. The edibility of the mushroom has not been determined. M. aurantiom arginata was included in a 2010 molecular analysis focused on clarifying the phylogenetic relationships between Northern European species in the section Calodontes.
It is common in Europe and North America, but has also been collected in North Africa, Central America, and Japan. The mushroom is saprobic, and produces fruit bodies that grow on the floor of coniferous forests. The cap color is variable, ranging from dark fuscous to yellowish-olive in the center, while the margin is orang-like. The flesh is thin and flexible with a decurrent tooth, and may spread that may spread when old. They are pallid to gray-olives with bright orange margins, brownish to grayish-OLive stipes, white spore deposit, and spiny cystidia. The spores are hygrophanous, but the overall color fades as the mushroom ages. The surface is moist, and young individuals are covered with whitish powder, but soon sloughs off.
