Description - what does it look like?
Growth: The Stinkhorn starts of in a spherical white egg. When sliced from top to bottom, the embryonic mushroom can be seen and looks almost lie a cat's eye with a white centre. The embryonic mushroom is surrounded by clear jelly
Fruitbody: After the fruit body emerges from the egg, it strongly resembles a human phallus. It has a hollow stem that resembles old polystyrene that has a stinky grey-black foul smelling goo at its top.
Flies feed on the goo, and once it has all been eaten and stuck to their bodies, a whitish honeycomb-like structure remains.
The fruit body is between 15 - 25cm in height and 2-5cm in width
Flesh: Off white
Smell: Rotting flesh when mature, none when in young egg stage
Spore colour: Black - foul smelling goo is spore mass
Possible lookalikes When in its egg stage, the Stinkhorn could be confused with young Amanitas, but these lack the layer of clear goo under the egg's skin.
Could also be mistaken for Earthballs, which are toxic, but these are purple or black inside, and, Puffballs, but these are pure white inside, or yellow to grey when gone over.
In addition, there are other Stinkhorn family members in the that it could easily be confused with that are considered either edible or inedible in the egg phase
Use as a food Young Stinkhorns in their egg stage are considered edible. In some countries they are pickled or dried. In our opinion, there are mush better wild mushrooms to consume!
Use in medicine Some research has shown Stinkhorn to be effective in treating thrombosis. In folk medicine, it has been used as an aphrodisiac and a cure for impotence
If you are suffering from any ailment or need medical advice, please see your General Practitioner

Hazards Do not consume once mature or in late egg stage when they are considered potentially toxic

Always stay safe when foraging. You need to be 100% sure of your identification, 100% sure that your foraged item is edible, and 100% sure that you are not allergic to it (it is good practice to always try a small amount of any new food you are consuming). If in doubt, leave it out!
