Mycena clavicularis is a small to medium-sized saprotrophic fungus with a bell-shaped cap that ranges from 0.5-2 cm in diameter, typically grayish-brown to pale brown in color. The gills are crowded and attached, with a similar color to the cap. Stems are slender, 1-4 cm long, and usually equal in width throughout. In East and Central Texas, Mycena clavicularis is commonly found growing on decaying wood, particularly oak and pine, in humid environments such as forests, wooded areas, and along streams. Fruiting bodies typically appear from spring to fall, with peak abundance during the summer months.
