Coprinopsis picacea
Coprinopsis picacea, commonly known as the magpie mushroom, magpie fungus, or magpie inkcap, is a species of fungus in the family Psathyrellaceae. It is toxic.
Taxonomy
The species was first described in 1785 by French mycologist Jean Baptiste François Pierre Bulliard in 1785 as Agaricus picaceus.Description
The cap is initially egg-shaped, then opens up to a bell shape up to wide. The cap is serrated and colored white on very young mushrooms. It breaks open with increasing age, revealing the dark brown background which becomes black. Remnants of the white, grayish to cream-colored velum remain on the cap as flakes, giving the impression of woodpecker or magpie plumage. With age, the brim of the cap rolls up and dissolves. The lamellae are mostly free, very close and are initially white, then reddening. Eventually they melt, dripping and black, hence the name inkcap.The stalk is whitish and 12–20 cm long and 6–15 mm thick. It is hollow and not very stable, slightly tapered towards the top and covered with scales or fine fibers. The flesh is whitish with a fibrous, watery consistency and sometimes has an unpleasant smell of moth powder. The taste is also unpleasant.
