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

Large dense clusters on stumps and dead wood, hardwood and conifer alike.

When to look

JFMAMJJASOND

Typically Jan to Dec 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.

Extremely common across the northern hemisphere, in almost every month.

What is worth knowing about it

Probably the most commonly encountered toxic mushroom in Europe, growing on any stump in any park. Causes serious gastrointestinal illness and, in large doses, has been implicated in liver damage. Its saving grace is that it is ferociously bitter, so few people finish a meal of 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.
