Lysurus mokusin is a small stinkhorn fungus, often called the lantern stinkhorn. It is listed among "medicinal fungi" in some fungus guides. There is no human evidence that it treats anything.
It starts life as a soft white or pink "egg" in the soil. The egg opens into a ribbed stalk with short arms at the top. The tip holds a brown, foul-smelling slime that draws flies, which spread its spores.
It grows on wood chips, bark mulch, garden beds and leaf litter. It is native to East Asia and now turns up in Europe, Australia and the Americas.
Traditional use is not proof that something works, and it is not proof that something is safe. Both points matter here, because the written record for this fungus is thin and modern. Treat this page as a map of what is not known as much as what is.
No one has shown how this fungus acts in the human body. There are no human studies to draw on.
Most claims are borrowed from other fungi. Lab work on related stinkhorns, such as Phallus species, has looked at polysaccharides (long sugar chains) from the fruit body.
In test tubes and in mice, some fungal polysaccharides appear to nudge immune cells. Whether that happens in people who eat Lysurus mokusin is not known.
The strong smell comes from sulfur compounds. In lab tests, sulfur compounds from various fungi can slow the growth of some bacteria. That is a test-tube finding, not a treatment.
So the honest answer is simple. The proposed mechanism is guesswork built on cousins of this species.
This is not a mainstream supplement. You will not usually find it in a pharmacy or health shop.
Where it is used at all, it shows up as:
- The fresh young "egg", cooked as a food in parts of East Asia. - Dried whole fungus, sold by specialist mushroom traders. - Rare powders or tinctures from small online sellers.
Labels on such products are often wrong. Dried stinkhorns are hard to tell apart once sliced. There is no agreed quality standard for any form.
Lysurus mokusin appears in East Asian fungus lists, including Chinese ones. Those records are modern and brief. They note the fungus and its habit more than any healing use.
In parts of China the young egg has been gathered and cooked as food. Folk sources have also mentioned stinkhorns in poultices for sores. These were local practices, written down late and lightly.
The better documented medicinal stinkhorn is the bamboo fungus, Phallus indusiatus. Lysurus mokusin has often been swept into the same category by name alone. That does not make the two interchangeable.
Stop and get medical help if you feel unwell after eating any wild fungus.
Go to an emergency department now if you have:
- Vomiting or diarrhoea that starts six or more hours after a mushroom meal. - Blood in vomit or stool. - Yellow skin or yellow eyes. - Confusion, drowsiness or fainting. - Passing little or no urine. - Swelling of the lips, face or throat, or trouble breathing.
Take a sample or a photo of the fungus with you. It helps staff identify what you ate.
It is not a controlled substance, and it is not licensed as a medicine in the United States, the United Kingdom or the European Union. Selling it as a food in the UK or EU would likely need novel food approval, which it does not hold.
