Mycena rubromarginata is a small to medium-sized agaric fungus with a bell-shaped to conical cap, typically 1-3 cm in diameter, and a slender stem. The cap is often reddish-brown to brown with a distinctive red or pinkish margin, while the gills are pale yellow to cream-colored. In St. Petersburg, Leningrad Oblast, and north-western Russia, Mycena rubromarginata has been found growing in clusters on decaying wood, stumps, and tree roots, often in moist, shaded areas of coniferous and mixed forests. Fruitings typically occur from late summer to early autumn.
