The sliminess of this Waxcap makes it both easy to identify but very hard to handle as it is slippery. Due to it being covered in slime it in considered inedible.

Slimy Waxcap possible confusion

Yellow Foot Waxcap (Cuphophylus flavipes), pictured, is very similar but not as slimy, the cap is not as evenly coloured and it has a yellow base of the stem.


Waxcaps don’t like to be disturbed or sprayed so will be found where fields and woodland have been left alone.
It is now thought that waxcaps grow in association with mosses, before it was thought that waxcaps were saprophytic living or decaying organic matter.
