The inky cap mushroom, also known as the shaggy mane, is a unique fungus that is well-known for its unusual look and fascinating behavior. This mushroom has several synonyms including lawyer's wig mushroom, black bonnet, bell-shaped shaggy cap, and coprinus comatus. The name 'lawyer's wig mushroom' is derived from its appearance, which resembles an old-fashioned wig worn by lawyers a few centuries ago. The 'bell-shaped shaggy cap' is derived from the distinctive shape of the mushroom cap, which tapers down towards the stem. And the 'black bonnet' refers to the black color of the mushroom cap, which is produced by the inky fluid that drips down as it matures.
