Lookalikes to rule out

Psilocybe species

deadly

People seeking psychoactive mushrooms have eaten conecaps; Psilocybe spores are purple-brown.

Galerina also contains amatoxins and has rusty-brown spores.

Identification

The cap is small, rarely over 2.5 cm, conical to bell-shaped, and orange-brown. Gills are rusty brown. The thin, fragile stem carries a small movable ring. It fruits in lawns, mulch, and wood chips.

Why it matters

This tiny mushroom contains the same amatoxins as the death cap. It is a particular risk to young children and dogs who eat mushrooms in lawns and landscaping.

Memorable fact

It is one of the smallest mushrooms known to carry enough amatoxin to endanger a person.
