Galerina hypnorum is a species of agaric fungus in the family Hymenogastraceae. The species has a hygrophanous cap measuring 4-15 mm in diameter, initially conical and becoming broadly convex with age. When moist, the cap is honey-yellow to ochraceous tawny, fading to buff or tawny brown as it dries. The surface is striate when wet and glabrous to faintly fibrillose.
