Mycena pura, commonly known as the lilac bonnet,[1] is a species of mushroom in the family Mycenaceae. First called Agaricus prunus in 1794 by Christian Hendrik Persoon, it was assigned its current name in 1871 by German Paul Kummer.[2] Mycena pura is known to bioaccumulate the element boron.[3]
The cap ranges from 1.5–5 cm (0.5–2 in). The stalk is 2–7 cm (0.79–2.76 in) tall and 3–7 mm wide. The spores are white.[4]
Similar species include Clitocybe nuda, Laccaria amethysteo-occidentalis, and Mycena purpureofusca.[4]
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 mycotoxin muscarine, and the antifungal metabolite strobilurin D, the latter previously found in Cyphellopsis anomala.[5] Despite the presence of these toxins,[6] some guides list M. pura as edible.[7]
