Never eat a wild mushroom identified from a website. This one helps you rule things out. It cannot rule anything in.

Edible, with conditions

Shaggy mane, lawyer's wig

Coprinus comatus

The character that does the work

A tall shaggy white cylinder in disturbed grass. Once it starts to blacken at the edge, it is a mushroom you look at rather than eat.

The specimen sheet, in examination order

How to take one

06Where it grows

Disturbed ground, grass verges, wood chips, playing fields, and famously through tarmac.

When to look

JFMAMJJASOND

Typically May to Nov in the northern hemisphere. Fruiting swings by weeks with rainfall and by a month or more with latitude, so this is when to look rather than when it will be there.

Widespread in the northern hemisphere.

What is worth knowing about it

Excellent, and on a clock. It begins to autodigest within hours of picking, so it must be cooked the same day, ideally within a couple of hours. Unlike the common inkcap it carries no alcohol interaction, but the two grow in the same places and are worth separating: the shaggy mane is tall, white and scaly, the common inkcap grey and smooth.

Confused with

  • Common inkcap
  • Magpie inkcap

In the kitchen

Cook the day you pick, whole or halved, in a dry pan first. Refrigerating overnight gets you black soup. It makes an outstanding soup precisely because it collapses.

The techniques, and why they work

This page tells you what to check. It does not tell you the mushroom in your hand is that species, and it cannot. If you are not certain, do not eat it. If you have already eaten something and feel unwell, contact a poison centre and keep an uncooked specimen.
