About Mycena pura (Pers.) P.Kumm.
Mycena pura is a tiny to medium-sized mushroom that grows in a wide range of colors, most often with purple undertones. Its cap measures 2 to 6 centimetres (3⁄4 to 2+1⁄4 inches) across; when young, it is violet to purple, but may change color as it ages. The cap can be convex, flat, or bell-shaped. The gills are pale or pinkish, and develop cross veins as they mature. The stem is 4 to 10 cm (1+1⁄2 to 4 inches) long and 2 to 6 millimetres (1⁄8 to 1⁄4 inches) thick. It matches the cap in color, is hollow, and bears no ring. This mushroom has a radish-like scent. Its spores are white, and it produces a white spore print. It emits faint bioluminescence that can be seen at night. It is widely distributed across North America, where it grows in decomposing forest litter under conifers, and occasionally under hardwoods. Mycena pura is known to bioaccumulate the element boron. It contains the toxin muscarine, so it should not be eaten. It does not appear to have any psychedelic properties. Despite containing toxins, some field guides list M. pura as edible.
