Mycena pura


Mycena pura, commonly known as the lilac mycena, lilac bonnet, is a species of mushroom in the family Mycenaceae.

Taxonomy

First called Agaricus prunus in 1794 by Christian Hendrik Persoon, it was assigned its current name in 1871 by German Paul Kummer.

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 in size. 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 long and thick. 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 and produce a white spore print.
It produces a faint bioluminescence, visible at night.

Similar species

Similar species include Clitocybe nuda, Laccaria amethysteo-occidentalis, M. purpureofusca, and M. pelianthina.

Distribution and habitat

It is widely dispersed across North America and can be found beneath conifers or occasionally hardwoods as decomposing forest litter.

Ecology

Mycena pura is known to bioaccumulate the element boron.

Toxicity

Given that it includes the toxin muscarine, it should not be consumed. M. pura does not appear to have any psychedelic characteristics.
Despite the presence of toxins, some guides list M. pura as edible.

Bioactive compounds

Mycena pura contains the chemical puraquinonic acid, a sesquiterpene. This compound induces mammalian cells to differentiate into granulocyte- or macrophage-like cells. The fungus also contains the antifungal metabolite strobilurin D, previously found in Cyphellopsis anomala.
