Potential lookalikes


Other Russulas but these have brittle gills rather than the charcoal burners flexible ones.
The stems of other Russulas stain salmon pink when rubbed with iron salts whereas the burner stains slightly green.

-Snap – Does the stem snap like a piece of chalk?
-Flick – Do the gills break when you flick them gently?
-Peel – Does the skin on the cap peel away?
-Taste–  this should only be done when you have gone through the other steps and are confident that you have a Russula. If a tiny amount placed on the tongue a chilli like burn or tingle means the mushroom is poisonous but a pleasant mushroomy taste means it is edible.


When applying this four step process you should not get brittle gills as the Charcoal Burner does not exhibit them.
