Stinkhorn
This mushroom first appears as an egg, partly submerged in the surrounding substrate with a jelly like feel. The mushroom then (slowly) bursts out and forms the very phallic looking fungi. The cap is covered in a sticky substance, called a gleba containing the spores, to which flies seem very attracted. As they devour this, they get covered in spores, which then get a free ride to a new place to grow.
You can often smell a stinkhorn before you see it!

Scientific Name | Phallus impudicus |
Season Start | Jun |
Season End | Nov |
Average Mushroom height (CM) | 25 |
Average Cap width (CM) | 5 |
Cap
At first appearing smooth and olive grey brown to black, this is what’s called the gleba, which contains the spores. As soon as flies find this mushroom they devour and get covered in it, leaving a white honeycomb like cap. In the adjacent image the gleba has been half devoured.
Bulbous Base
Has a very bulbous almost volva like base, that when in the egg stage, contains a small Stinkhorn fruitbody, surrounded by a slimy jelly.
Possible Confusion
Can look a bit like a Black Morel or False Morel but the overwhelming stench of the Stinkhorn should save confusion.
Can also look like a Puffball, Earthball, pictured, or Amanita egg when in the egg stage, but Puffballs are soft, spongy and pure white inside, Earthballs are tough and usually purple or black inside, Amanitas at the egg stage will have a small fruiting body inside, but it is not surrounded by slime and again the smell should help you avoid any confusion.
Spore Print
Pale yellow. Oblong. As the spores are mixed in the olive grey gleba, it is not possible to do a spore print with this mushroom.
Taste / Smell
At the egg stage, this mushroom is reported as edible. The tough cuticle in the egg does taste a bit like radish, but we don’t eat this mushroom as the smell is putrid and most unappetizing.
Frequency
Common.
Other Facts
This mushroom has been reported to have aphrodisiac qualities, but this is purely down to it’s phallic look, rather than anything scientific.
Victorians were disgusted by the sight of this mushroom and used to go out in the morning with a club and flatten them to save young women’s embarrassment.

Saw around three or four stink-horns in a rhododendron maze at Castle Semple Country Park, Renfrewshire, Scotland. Definitely stink-horns but no smell!
Ditto at Sandringham in Norfolk today. They looked great but no strong smell… Covid? 🙂
Some of these have popped up in my garden I Reading, Berkshire this week, not the most attractive but at least there’s no smell
Just tracked down the source of an appalling smell in the garden 1 stink horn living up to its name.Have never seen( or smelt! ) one before.Dunbar countryside,East Lothian
Find one at the base of a rotting ash stump today in Henfield West Sussex. Mostly devoured but still attracting a lot of flies
Can anyone describe what the smell is like please? I think we have some in our garden but wanted to be sure before we investigate!
It is a very unpleasant smell, a bit like sewage or rotting flesh but not quite the same.
Have some growing in my mulch the smell is sickning almost makes you want to puke. Strong like sewage
Wondered what the awful smell was, then spotted one of these by the gate. Limousin, France.
Sniffed a couple out in the woods today near Stocks Reservoir and found one Stinkhorn Egg.
The egg has no smell even when cut open.
Sliced up and dry fried it certainly has a mild unique flavour all of its own and a crunchy radish like centre.
I have a photo of the egg stage if you would like it for this site.
I have them in my yard, but they smell earthy not bad. came on mulch CT
This morning me and my momma found some stinkhorn mushroom’s. We had no clue what they were but she found them on Google. (Gotta love goggle). The ones we found look like a orange 🥕carrot with brownish black on the head. So not pretty but interesting. So far there is no smell, wish I could send picture…..They are actually scarry looking. Well Halloween is around the corner Freddy Gruger has nothing on these. Will post pictures if I can. Enjoyed reading all the replies, it’s nice to know we’re not alone. Blessings to all, and to God in whom we trust. May peace ✌️ reign upon all the land and in our lives.
We have one growing in our flower bed in Southern Indiana, had never seen one before. Oct. 26th
When I was a student I found the “egg” stage, dug it up and took it back to my room in a plant pot so I could watch it mature. It was fascinating watching it expand after a couple of days to the phallic form in around an hour. It also quickly lived up to its stinkhorn name. Rotting flesh is a good description, though there’s an unmistakeable acrid odour which I can always now recognise.
Found lots of these today in a spruce forest .a great find in mid November
Found one yesterday in North warwickshire in a very small woodlands, one very prominant and about 7 inches coming out of the ground. a few other broken down stink horns in the area that look like polystyrene. Very large volva coming out of the ground, with the cap being about 2-3 inches tall, and the whole cap brown and tar like!
Very very stinky! didnt catch the smell until i was up close but then could smell it up to a meter away, Smelt like very fresh dog poo! I have some good photos of the shroom so please do let me know if anyone would like to see it. 🙂
We have recently moved to a house with quite a wild garden in Crieff and I found three eggs by the roots of an ash tree last week. I had no idea what they were but phallus impudicus does grow round here and I saw them on a woodland edge not far from the house last year so I was very pleased to be able to identify them.
Our garden backs onto a woodland area associated with a local nursing home. Over a period of several years (about June time) we could smell this strong odour at the end of our garden. We assumed that the smell came from dying/decaying rats or similar, that had been killed by poison put down by staff at the nursing home because of infestation near their kitchens. Today, 6th July, we discovered what we now know to be a stinkhorn mushroom, covered in flies, growing in our runner bean patch, at the top end of our garden! The smell is exactly the same as we had experienced before.
These are generally super tasty but only when picked within specific few hours right after they ‘come out of egg’ and before stage when they attract flies.
Just found two in my garden. Very smelly but not really stinking. Reminding me somewhat of the odor of flowering sweet chestnut.
found a few those devil eggs, awesome taste (raw egg centre), frying on a bit of butter make a nice snack – taste and looks v cool
Lots of these in Thetford Forest today, although I think its a bit too cold for them and maybe a quarter of them mature to stage where cap gets black, rest of them just die with slightly greyish cap.
Last year I found what I thought was a reptile egg in my garden in North Devon. This year whilst sitting on the patio could smell what I imagined was a dead rodent of some sort. However I have now found the source of the stink. Yes its several STINKHORNS.
Just come across a fair few of these and some Panther Caps in Parkham forest, North Devon.
All have popped up after a five week draught followed by a torrential downpour. Their smell was what allowed me to find them!
are they poisonous? do they indicate rotting tree roots?
They are not poisonous just inedible due to the taste and smell. They do not rot the roots of trees.
We have a dozen orange ones growing in our park in Florida. They certainly do have a bad aroma.
Found a couple in my garden in Edinburgh yesterday. More of a cream colour with a brown top but no smell… Have lived here for over 40 years and have never seen them before. We’ve just had a spell of very wet weather over several weeks. Wondering if they are Stinkhorns or not…..
If you can send in some photos we will try to identify them for you. Send them to [email protected]
At the back of the garden here in Edinburgh, about five days ago, I came across a circular, slightly yellow tinged clear jelly object of about 8cm in diameter raised about 1cm above ground level. There were remnants of what must have been a leathery skin on the periphery of the jelly. In the middle, submerged by about a centimetre was a white domed mass of about 5cm in diameter resembling the top of a hard boiled egg. My wife checked on it last night but it nothing had changed but for the fact that the jelly had yellowed slightly. I checked about an hour ago at lunch time and it hade emerged. The head was a matt green/brown of about 6cm long and 4cm diameter sitting on top of white stem of about 11cm long and 2.5cm diameter. There is some smell but as compared to a fox that died under our garden hut a few days ago it is mild. As flies feed on the head they reveal a slimy texture beneath the matt surface. As the slime is eaten away a white crenelated/cupped surface is revealed. I have a decent photograph this fungi along side a ruler for scale.
I just spotted a stinkhorn in my garden today. All summer I have been plagued by flies. Its been unbearable to be in the garden at times as you end up with a swarm of flies buzzing around your head and trying to fly into your ears! I wondered if there was something dead in the woody area of my yard that has attracted them. But now learning about stinkhorns I wonder if that is the source of them. Maybe I’ve had an outbreak of stinkhorns that has attracted so many flies. The neighbours must think I have tourrettes as they persistently try to enter my ears!!
It could be the Stinkhorns but they usually have to break through the ground before they smell and attract flies. I hope your neighbours are understanding about your strange movements!
