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

Deadly galerina

Galerina marginata

The character that does the work

A rusty-brown spore print on a small brown mushroom growing from rotten wood. There is no field character that settles this one. Take the print.

Amanitin, a cyclic peptide that shuts down RNA polymerase II

The false recovery is the reason people die. Anyone who ate wild mushrooms and became ill the NEXT DAY needs a hospital, however well they feel by the time they get there. Cooking, drying and freezing do nothing to the toxin.

Amatoxin poisoning, in full

The specimen sheet, in examination order

01Cap

2 to 4 cm, small, tawny to rusty brown, smooth, becoming paler and buff as it dries out from the centre.

02Underside

Attached rusty-brown gills, moderately spaced.

03Stem, and the base

Thin, brownish, usually with a thin ring or a ring zone that collects rusty spore dust.

04Flesh, cut

Thin, brownish.

05Spore print

Brown to rust

Rusty brown, and this alone separates it from the honey mushroom it grows beside.

How to take one

06Where it grows

On well-rotted wood, chiefly conifer, in small clusters or scattered groups.

When to look

JFMAMJJASOND

Typically Aug 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.

Common across the northern hemisphere.

What is worth knowing about it

Contains the same amatoxins as the death cap in a mushroom small enough that nobody takes it seriously. It kills experienced foragers, most often people harvesting honey mushrooms in bulk from wood, and people hunting small brown mushrooms for other reasons.

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.
