Mycena viridimarginata is a species of mushroom characterized by its small to medium size, bell-shaped cap, and greenish-blue margin. In St. Petersburg, Leningrad Oblast, and north-western Russia, it typically grows in clusters on moss, litter, or soil in coniferous and mixed forests, often associated with spruce and pine trees. The fungus fruits from late summer to early autumn, with a preference for humid, shaded environments. Its cap is 1-3 cm in diameter, initially convex then becoming flattened, with a vibrant green to blue-green margin and a pale brown to grayish-brown center. The gills are narrowly attached, crowded, and pale yellowish-gray, while the stem is slender, hollow, and powdery, measuring 2-5 cm tall and 0.1-0.3 cm thick.
