Orange Mycena is a common, colorful, bonnet mushroom. It occurs in North America east of the Great plains and in the Pacific Northwest, and in Mexico and Central America. A variety of this species occurs in eastern Australia and New Zealand. It is found from June through September in woodlands, growing on the dead wood of deciduous trees. It obtains its nutrients from decaying wood (saprobic). It almost always forms tight clusters, with several stems arising from the same point. It is rarely found alone. When handled, the orange pigment will stain the skin.

The cap on young specimens is oval or bell-shaped, bright reddish-orange, shiny, hairless, and sticky. The margin is curved inward. As it ages the cap flattens out, becoming broadly bell-shaped or convex to nearly flat, sometimes with a small depression in the middle. The color fades to bright orange, then paler and more yellowish. The margins sometimes become lined. The upper surface is dull and dry but becomes sticky when wet. Mature caps are to 1½ (1 to 4 cm) in diameter. Older caps are sometimes almost white.

The stalk is slender, 1¼ to 2¾ (3 to 7 cm) long, and 116 to (2 to 4 mm) thick. It is often curved or wavy and is sometimes flared at the top. It is tough, cartilaginous, hollow, and sticky when wet. The color is the same as the cap, but it is often paler near the top. It is smooth except rough to the touch just near the top when young. The base is covered with long, stiff, orange hairs. When squeezed, it exudes a watery orange juice.

The gills are closely spaced or crowded. They are broadly attached (adnate) or notched at the point of attachment. The surfaces are pale orange or salmon-colored, but the edges are brilliant reddish-orange. They stain orangish-yellow when bruised.

The flesh is thick, yellowish-white, and watery. Edibility is unknown, but all descriptions mention that the taste is “mealy”, “not distinctive”, or “lacking”.

The spore print is white.
