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

How to take one

06Where it grows

Wood chips, garden mulch, straw beds. Almost always on ground that a person has disturbed.

When to look

JFMAMJJASOND

Typically May to Oct 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.

North America and Europe, spread widely by landscaping mulch.

What is worth knowing about it

The easiest mushroom to cultivate outdoors by a wide margin: spread spawn in a mulch bed and it fruits for years with no further attention. That makes it the practical answer for anyone who wants wild-tasting mushrooms without the identification risk.

Confused with

  • Various dark-spored mulch species

In the kitchen

Young firm buttons are the ones to take. Larger specimens go soft. It is one of the better mushrooms for the grill because the flesh is thick enough to survive it.

The techniques, and why they work

Growing it

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.
