Taxonomy
First called Agaricus prunus in 1794 by Christian Hendrik Persoon, it was assigned its current name in 1871 by German Paul Kummer.[3]
Description
Mycena pura is a tiny to medium-sized mushroom that can grow in a variety of hues, frequently with purple undertones. The cap ranges from 2 to 6 centimetres (3⁄4 to 2+1⁄4 in) in size.[4] It is violet to purple when young but can change color with age. It can be convex, flat, or bell-shaped. The gills are pale or pinkish in color and get cross veins as they age. The stem is 4 to 10 cm (1+1⁄2 to 4 in) long and 2 to 6 millimetres (1⁄8 to 1⁄4 in) thick.[4] It is colored like the cap, hollow, and the same shade. There is no ring on the mushroom. It has a radish-like scent. The spores are white[5] and produce a white spore print.[6]
It produces a faint bioluminescence, visible at night.[7]
Similar species
Similar species include Clitocybe nuda, Laccaria amethysteo-occidentalis, M. purpureofusca,[5] and M. pelianthina.[6]
Distribution and habitat
Ecology
Mycena pura is known to bioaccumulate the element boron.[8]
Toxicity
Bioactive compounds
Mycena pura contains the chemical puraquinonic acid, a sesquiterpene. This compound induces mammalian cells (specifically, the cell line HL60) to differentiate into granulocyte- or macrophage-like cells. The fungus also contains the antifungal metabolite strobilurin D, previously found in Cyphellopsis anomala.[9]
