Learn these to avoid them

This tier runs from mushrooms that cause a miserable night to a few that can kill. Knowing them by sight is the core skill of safe foraging.

Toxic is not the same as deadly

Many poisonous species cause severe cramps and vomiting but pass. A small number, led by the death cap, destroy the liver and can be fatal.

The habits that keep you safe

Study the deadly lookalikes of anything you forage, check every feature including the base of the stem, and when you are not certain, throw it out.
