False turkey tail
Stereum ostrea (related: Stereum hirsutum) · also called Hairy curtain crust is the related Stereum hirsutum, a separate species
False turkey tail is a tough, leathery wood fungus that looks like turkey tail but is a different fungus. It is not a food and we found no supplement made from it. The research is test-tube and cell-dish chemistry only, with no studies in people. Turkey tail research does not apply to it.

About False turkey tail
False turkey tail is a thin, tough, banded bracket fungus on dead hardwood. It is named for its likeness to turkey tail, and it is not turkey tail. It is not a food, we found no supplement made from it, and there are no human studies. The research is chemistry done on lab cultures, extracts and cells. Do not use a wild fungus unless an expert has identified it.
What it is, and how it differs from turkey tail
Stereum ostrea belongs to the family Stereaceae, a group of wood-decay fungi. GBIF lists it as an accepted species, and also lists Stereum hirsutum (hairy curtain crust) as a separate accepted species. A Korean paper says the fungus grows in dense overlapping clusters on dead hardwoods, is inedible because of its tough, leathery texture, and is often called false turkey tail because it mimics turkey tail (Trametes versicolor).
Turkey tail is a different fungus, from a different group, and its research is about specific extracts known as PSK and PSP. None of the abstracts we read reports those compounds in Stereum, and no paper compares the two. So nothing found for turkey tail can be assumed for false turkey tail. Read the turkey tail page to see what that research does and does not show.
The related hairy curtain crust has its own chemistry. Where this page uses a result from it, the page says so.
What the research shows
Nothing has been tested in people. In 2007 a Korean group found that water and ethanol extracts of lab-grown Stereum ostrea slowed several bacteria and plant fungi on agar plates, at very high concentrations. A 2012 survey found a methanol extract of wild S. ostrea was antioxidant in chemical tests.
Chemists have also isolated compounds from S. ostrea cultures. Two ostalactones strongly blocked a fat-digesting enzyme in a test tube, and sterostrein A acted on cancer cell lines and the malaria parasite in culture. A 2020 review counts 238 compounds from the whole genus, most with lab activity only.
These results show interesting chemistry. They cannot show a health effect, because test-tube and cell-dish results often fail in people.
How strong is the evidence?
Every result is rated not enough evidence. It is lab work on pure compounds, cultures and extracts, mostly from abstracts, and it mixes two species. Culture extracts and fruiting-body extracts also behave differently: in a 2025 Polish screen, hairy curtain crust fruiting-body extracts were mostly inactive against five bacteria.
Forms and products
We found no consumer product made from false turkey tail, so we cannot say what one would contain. The lab work used cultures, pure compounds and solvent extracts, which are not tea, powder or capsules. For medicinal mushrooms in general, NCI says supplement ingredients may vary considerably from lot to lot. If a turkey tail product names Stereum rather than Trametes versicolor, ask the seller for proof of what is in it.

Germs in the lab (agar plates only)
Not enough evidenceExtracts of lab-grown Stereum ostrea slowed several bacteria and plant-disease fungi on agar plates. Fruiting-body extracts of the related hairy curtain crust were mostly inactive against five bacteria in a Polish screen. None of this was tested in animals or people.
3 studiesLab-grown culture filtrate and water, ethanol or methanol extracts. N…
Studies, doses and limits
Results
S. ostrea (culture extracts, Korea, 2007): water and ethanol extracts inhibited Gram-positive and Gram-negative bacteria; inhibition zones against Staphylococcus aureus were 23.6 mm (water) and 21.0 mm (ethanol); MIC 10 mg/ml for Bacillus subtilis and 40 mg/ml for two plant fungi. S. hirsutum (fruiting-body methanol extracts, Poland, 2025): three of four samples inhibited none of five bacteria; one inhibited one bacterium at 25 mg/mL.
Effect sizes as reported
Agar-plate inhibition at milligram-per-millilitre concentrations; no effect size in a body
Why this rating
Laboratory agar-plate work only, mostly on lab-grown culture, at very high concentrations, with results that differ between culture and fruiting body. No animal or human data.
Form and dose studied
Lab-grown culture filtrate and water, ethanol or methanol extracts. None of these is a product people can buy.
Who was studied
Bacteria and plant-disease fungi on agar plates
Limits
Two species (S. ostrea and S. hirsutum) in two different papers; culture versus fruiting body differ; concentrations are very high; no animals or people.
Why researchers looked
Wood fungi make chemicals to fight other microbes, so researchers screen them for germ-killing compounds.
Traditional use
One paper says the fungus has long been used for folk remedies but names no region, preparation or disease. We do not treat that as evidence.
Proposed mechanism Laboratory research
Not worked out in the abstracts. The 2020 review lists antibacterial and antifungal compounds in the genus (for example sesquiterpenes and vibralactones).
A proposed mechanism does not show that the effect happens in people.
No human safety data were found. See the Safety tab. Do not eat or use a wild fungus unless an expert has identified it.
Antioxidant tests (chemical tests only)
Not enough evidenceIn chemical tests, methanol extracts of wild S. ostrea and water or methanol extracts of S. hirsutum mopped up test radicals. A chemical test in a tube does not show a benefit in a body.
2 studiesMethanol, ethanol and water extracts made in a lab. Not a tea, powder…
Studies, doses and limits
Results
S. ostrea (wild-collected, methanol extract, Korea, 2012): potent antioxidant activity in all three chemical tests (ABTS, DPPH, reducing power); no figures in the abstract. S. hirsutum (extracts, Serbia, 2021): highest antioxidant activity in the polar (methanol and water) extracts.
Effect sizes as reported
Test-tube activity only; no figures in the abstracts
Why this rating
Two abstract-only chemical studies on two different species; the same extract that was antioxidant in the tube was also toxic to cells in the second study.
Form and dose studied
Methanol, ethanol and water extracts made in a lab. Not a tea, powder or capsule people can buy.
Who was studied
Chemical tests
Limits
Abstracts only; no numbers; different species; a chemical test cannot show benefit in people.
Why researchers looked
Antioxidant chemical tests are cheap and are run on many mushrooms.
Traditional use
One paper says the fungus has long been used for folk remedies but names no region, preparation or disease. We do not treat that as evidence.
Proposed mechanism Laboratory research
The ABTS and DPPH tests measure whether an extract can neutralise a test radical in a tube. They do not measure what happens in a body.
A proposed mechanism does not show that the effect happens in people.
No human safety data were found. See the Safety tab. Do not eat or use a wild fungus unless an expert has identified it.
Any use in people
Not enough evidenceWe found no human trial, case report, animal study of a health outcome or safety study of false turkey tail or hairy curtain crust. For every health claim the honest answer is: not enough evidence.
2 studiesNo consumer product was found.
Studies, doses and limits
Results
No human results to report.
Why this rating
No human study exists in the sources searched.
Form and dose studied
No consumer product was found.
Limits
Absence of evidence is not evidence of safety or of benefit.
Why researchers looked
Readers ask whether false turkey tail is a cheaper or wild version of turkey tail. Nothing shows that.
Traditional use
One paper says the fungus has long been used for folk remedies but names no region, preparation or disease. We do not treat that as evidence.
Proposed mechanism None
Not applicable.
A proposed mechanism does not show that the effect happens in people.
No human safety data were found. See the Safety tab. Do not eat or use a wild fungus unless an expert has identified it.
A fat-digesting enzyme (test tube only)
Not enough evidenceTwo pure compounds from the culture broth of Stereum ostrea strongly blocked human pancreatic lipase, an enzyme that digests fat, in a test tube. Nobody has tested the fungus or the compounds in animals or people.
1 studiesPure compounds isolated in a lab. Not a food, tea or supplement.
Studies, doses and limits
Results
Ostalactones A and B (pure compounds from Stereum ostrea culture broth, 2016) displayed potent inhibitory activity against human pancreatic lipase. No numbers in the abstract.
Effect sizes as reported
Test-tube activity only
Why this rating
One abstract-only enzyme assay of pure compounds from a lab culture.
Form and dose studied
Pure compounds isolated in a lab. Not a food, tea or supplement.
Who was studied
Isolated enzyme
Limits
Pure compounds in a tube; no animal or human data; amounts in the fungus unknown.
Why researchers looked
Lipase blockers are a drug target for weight control, so chemists test natural compounds against the enzyme.
Traditional use
One paper says the fungus has long been used for folk remedies but names no region, preparation or disease. We do not treat that as evidence.
Proposed mechanism Laboratory research
The compounds (ostalactones A and B) are lactones that blocked the enzyme in an assay. The abstract gives no figures.
A proposed mechanism does not show that the effect happens in people.
No human safety data were found. See the Safety tab. Do not eat or use a wild fungus unless an expert has identified it.
Cancer cells and malaria parasite in a dish
Not enough evidencePure compounds from cultures of Stereum ostrea (sterostrein A) and Stereum hirsutum (sterhirsutins) were toxic to cancer cell lines, and sterostrein A acted on the malaria parasite, in dishes. This shows the compounds are biologically active. It does not show a treatment.
3 studiesPure compounds from lab culture.
Studies, doses and limits
Results
Sterostrein A (S. ostrea culture, 2011): antimalarial activity (IC50 2.3 micrograms/mL) and cytotoxicity (IC50 5.3 to 38 micrograms/mL). Sterhirsutins C-L (S. hirsutum culture, 2015): cytotoxic against K562 and HCT116 cell lines; compound 9 induced autophagy in HeLa cells; compound 5 inhibited the IFN-beta promoter in virus-infected cells. The 2020 review lists cytotoxic, antiviral, autophagy-inducing and worm-killing compounds in the genus.
Effect sizes as reported
Cell-dish IC50 values for one pure compound; no whole-body effect
Why this rating
Cell-dish chemistry on pure compounds from cultures of two species; no animal or human data. Cytotoxic means harmful to cells.
Form and dose studied
Pure compounds from lab culture.
Who was studied
Cell lines and a parasite in culture
Limits
Abstract-only; different species in the two papers; cell toxicity is not a treatment and may harm healthy cells too.
Why researchers looked
Natural-product chemists test new compounds on cancer cell lines and parasites as a routine screen.
Traditional use
One paper says the fungus has long been used for folk remedies but names no region, preparation or disease. We do not treat that as evidence.
Proposed mechanism Laboratory research
Sterostrein A killed cells and parasites in culture; one S. hirsutum compound induced autophagy in HeLa cells and another dampened an immune signal in virus-infected cells. Cells in a dish are not a body.
A proposed mechanism does not show that the effect happens in people.
No human safety data were found. See the Safety tab. Do not eat or use a wild fungus unless an expert has identified it.
A nerve enzyme linked to memory (S. hirsutum, test tube only)
Not enough evidenceAn ethanol extract of the related hairy curtain crust blocked acetylcholinesterase, an enzyme that drugs for Alzheimer's disease also block, in a test tube. The same extract was toxic to liver cancer cells in a dish. This does not show any benefit for memory.
1 studiesEthanol extract made in a lab.
Studies, doses and limits
Results
Stereum hirsutum ethanol extract (2021): acetylcholinesterase inhibition 98.44 %; toxic to HepG2 cells (91.96 % at 900 micrograms/mL).
Effect sizes as reported
Test-tube inhibition and cell toxicity; no body data
Why this rating
One abstract-only laboratory paper on a related species. The authors' suggestion of a supplement for Alzheimer's care goes well beyond the data.
Form and dose studied
Ethanol extract made in a lab.
Who was studied
Enzyme and liver cancer cells
Limits
Different species from false turkey tail (S. ostrea); lab only; cell toxicity in the same extract.
Why researchers looked
Researchers look for natural enzyme blockers when searching for Alzheimer's drug leads.
Traditional use
One paper says the fungus has long been used for folk remedies but names no region, preparation or disease. We do not treat that as evidence.
Proposed mechanism Laboratory research
The extract inhibited the enzyme in an assay. The authors link this to phenolic acids, fatty acids and the biflavonoid amentoflavone.
A proposed mechanism does not show that the effect happens in people.
No human safety data were found. See the Safety tab. Do not eat or use a wild fungus unless an expert has identified it.
As a food

Evidence at a glance: what the research found for 7 outcomes
Each outcome below is one thing researchers measured. Certainty is how far the evidence can be trusted, not how well it works. The full studies are on the next tab.
The evidence
The research centre for False turkey tail. Every record here was checked against PubMed or the publisher's page; we never list a study we have not verified.
Evidence by outcome
Bars show how many studies we found for each outcome, not how well it works. People are added up across trials only (reviews are not added, to avoid double counting).
How we rate evidence
High certainty
Several well-run trials or reviews agree; further research is unlikely to change the picture much.
Moderate certainty
Good trials point the same way, but some doubt remains.
Low certainty
Small, short or inconsistent trials. The finding could change with better research.
Very low certainty
Very little or very weak human data. Treat as a possibility only.
Mixed findings
Trials or reviews disagree with each other.
Not enough evidence
Not enough human research to say either way.
Evidence against
Good research found no benefit, or found harm.
We take the reviewers' own risk-of-bias and GRADE statements where they exist, and otherwise judge from study size, design, consistency, directness and whether a product matches what is sold. Many publications do not make evidence high. Method note: We read PubMed records and abstracts for 9 papers on Stereum ostrea and Stereum hirsutum (laboratory, chemistry and review papers) and read the open full text of two of them, checked the names in GBIF, and read the National Cancer Institute medicinal mushrooms page. LiverTox and LactMed were searched through NCBI Books and nothing was found. Certainty ratings are the compiler's own reading.

Laboratory study (agar plate tests) Stereum ostrea (culture) |
Five bacteria and three plant-disease fungi on agar plates | Liquid culture filtrate, and water and ethanol extracts of solid culture of S. ostrea Lab-grown culture (not wild fruiting bodies) |
Water and ethanol extracts of lab-grown culture inhibited both Gram-positive and Gram-negative bacteria, and the water extract did better than the ethanol one. Inhibition zones against Staphylococcus aureus were 23.6 mm (water) and 21.0 mm (ethanol), and against Pseudomonas aeruginosa 26.3 mm and 22.3 mm. The lowest growth-stopping concentration (MIC) was 10 mg/ml for Bacillus subtilis and 40 mg/ml for two Colletotrichum plant fungi. The water extract was the best against the plant fungi. The full text (read through Europe PMC on 2026-10-25) says the fungus is inedible because of its tough, leathery texture, is often called 'False turkey tail' because it mimics Trametes versicolor, and 'has long been used for folk remedies' with no region, preparation or disease given.

Laboratory study Stereum hirsutum (extracts) |
Extracts tested in test tubes and on HepG2 liver cancer cells | Water, ethanol, methanol and polysaccharide extracts Mushroom (part not stated in the abstract) |
The ethanol extract was the most potent at blocking acetylcholinesterase (98.44 %) and was toxic to HepG2 cells (91.96 % at 900 micrograms/mL). The best antioxidant activity came from the polar (methanol and water) extracts. The main fatty acid was linoleic (40.00 %); the authors report phenolic acids and the biflavonoid amentoflavone. The authors call it a possible food supplement for Alzheimer's palliative care, which a test-tube study cannot support. Enzyme inhibition, antioxidant tests and cell toxicity Methods, limits and fundingOutcomes: Enzyme inhibition, antioxidant tests and cell toxicity Limitations: Test-tube and cell-dish work on a different species (S. hirsutum, not S. ostrea). The authors' supplement and Alzheimer's suggestion goes beyond the data. A strongly cell-toxic extract is a warning, not a benefit.

The abstract does not name Stereum. In the open full text (read through Europe PMC on 2026-10-25) four Stereum hirsutum fruiting-body samples were tested: three showed no inhibition of any of the five bacteria and one showed inhibition at 25 mg/mL for one bacterium. S. ostrea was not among the species tested. The authors note that cultures of S. hirsutum can be active when fruiting-body extracts are not. Antibacterial activity of crust fungi (S. hirsutum among them) Methods, limits and fundingOutcomes: Antibacterial activity of crust fungi (S. hirsutum among them) Limitations: Table read in the open full text; very high concentrations (25 to 50 mg/mL) were needed for full inhibition in the study overall.

What we do not know yet
- No human trial and no human safety study of false turkey tail or hairy curtain crust were found.
- No animal study of any health outcome was found.
- Most compounds come from lab cultures, and amounts in wild fruiting bodies are unknown.
- The lab papers cover two species (Stereum ostrea and Stereum hirsutum), so they cannot be combined.
- No test of heavy metals, pesticides or mould toxins. LiverTox and LactMed entries were not found; EMA, NCCIH and MSK pages were not checked.

Main points to know 5
- No human safety data were found. We found no clinical trial, case report, poison-centre report or allergy report for false turkey tail (Stereum ostrea) or hairy curtain crust (Stereum hirsutum). That means the risks are unknown, not that there are none. Nothing here is a safety all-clear. None 11 8
- It is not a food, and it is not turkey tail. The Korean paper that uses the name says the fungus is inedible because of its tough, leathery texture and that it is called false turkey tail because it mimics real turkey tail (Trametes versicolor). It is a different fungus in a different group. Research on real turkey tail (PSK, PSP and the cancer-care trials) does not apply to it. See the turkey tail pages. Identification caution 2
- Some Stereum compounds are toxic to cells and worms in tests. The 2020 review lists cytotoxic and nematocidal (worm-killing) compounds in the genus, and an extract of the related hairy curtain crust killed most liver cancer cells in a dish. That shows the chemistry is biologically active. It is not evidence of what happens if a person eats or takes the fungus. Laboratory research 11 3 7
- Wild fungus: identify with an expert, do not guess. Wild fungi cannot be safely identified from text, photos or apps, and this page gives no identification help. Look-alikes of turkey tail are common. Do not eat, brew or apply a wild fungus unless a trained local expert has identified it. Identification caution 2
- No known consumer product, so label quality cannot be judged. We found no supplement made from false turkey tail. For medicinal mushrooms in general, NCI says ingredients may vary considerably from lot to lot and there is no guarantee that label ingredients are present. A 'turkey tail' product should list Trametes versicolor; if it names Stereum, ask the seller for proof. Authoritative guidance 9
Side effects 1
| Effect | How often | Severity and recovery | Evidence |
|---|---|---|---|
| No adverse effects have been reported, but none have been looked for in people Absence of reports in the sources we read is not proof of safety. | Unknown | unknown Not applicable | None |
Liver
We found no case report or trial linking Stereum ostrea or S. hirsutum to liver injury. A search of NCBI Books on 2026-10-25 returned no LiverTox entry. One lab study found that an ethanol extract of S. hirsutum was toxic to liver cancer cells (HepG2) in a dish, which is a cell result and not a report in people. 8 7
How often. No liver reports found; this is not proof of liver safety.
Monitoring. No agency monitoring advice exists in the sources we read. People with liver disease should ask a doctor before using any medicinal fungus.
This is a safety connection. It is not evidence that False turkey tail supports liver health.
Medicines and supplements 3
| With | Why it matters | Importance | Evidence | What to do |
|---|---|---|---|---|
| Any medicine, including blood thinners and immune-suppressing medicines prescription | Unknown. No interaction study or case report was found. | None Not enough evidence | Ask your prescriber or pharmacist before using any medicinal fungus. | |
| Herbal products and other supplements supplement | Unknown. No interaction study or case report was found. | None Not enough evidence | Tell your pharmacist about every product you use. | |
| Food and alcohol food | Unknown. The fungus is not a food. | None Not enough evidence | Not applicable. |
Who should check first 4
| Situation | Advice | Evidence |
|---|---|---|
| Pregnancy and breastfeeding | No safety data were found, so it is not known whether it is safe. Ask a doctor. Our NCBI Books search found no LactMed entry. | None 8 |
| Children and babies | No safety data were found. A wild fungus eaten by a child needs medical advice. | None |
| Mushroom allergy, asthma or a history of reactions to fungi or moulds | Allergy to this fungus has not been studied. Take extra care and ask a doctor. This is general caution, not from a Stereum source. | General caution |
| Before surgery, or with immune disease or an organ transplant | Nothing is known. Ask your doctor before using any medicinal fungus. | None |
Overdose, product quality and regulators
Summary. No toxicity study in people or animals was found. Cell-dish and worm tests show that some Stereum compounds are toxic to cells.
Human doses studied. No human study. This page gives no amounts and none are advised.
Overdose response. No description was found. If someone becomes unwell after eating any wild fungus, seek medical help or call poison control and keep a sample if you can.
Toxic parts. Not described in the sources read.
We found no test of heavy metals, pesticides or mould toxins in these species. As a general rule, wild fungi can take up substances from the wood and surroundings.
Heavy metals and wild growth. No data for these species were found. This is a general caution about wild fungi, not a finding about false turkey tail.
Mislabelling in turkey tail products. We found no source reporting that Stereum has been sold as turkey tail. The risk is stated as a question to ask a seller about, not as something found.

When to get medical help
- Itching, hives, swelling of the lips, tongue or face, wheeze or trouble breathing after eating, handling or inhaling a fungus: get emergency help now (general advice, not from a Stereum source).
- Repeated vomiting, severe stomach pain, diarrhoea, confusion or yellow skin or eyes after eating any wild fungus: get medical help now and call your local poison control number (in the US, Poison Help 1-800-222-1222). Keep a sample of the fungus if you can.
- A wound that bleeds heavily, looks infected, or does not heal: do not rely on any fungus; get medical care.
If someone may be poisoned or in a crisis, contact a clinician or emergency service straight away. In the US, Poison Control is 1-800-222-1222.
General information only, not medical advice. Ask a clinician or pharmacist before use, especially with medicines, in pregnancy or with a health condition. See the Natural Remedy Safety guide.
Frequently asked questions
What is false turkey tail?
Is it the same as turkey tail?
No. Turkey tail is Trametes versicolor, a different fungus in a different group. Turkey tail research, including PSK and PSP, does not apply to false turkey tail, and no paper compares the two.
Is it edible?
It is described as inedible because of its tough, leathery texture. We found no food or safety data. Never eat a wild fungus because of a description.
Does it have proven health benefits?
Is false turkey tail safe?
Is hairy curtain crust the same thing?
Does it fight germs or infections?
Is it an antioxidant?
Only in chemical tests. A methanol extract of wild Stereum ostrea scored well in three tube tests, but a chemical test does not show a benefit in a body.
Does it treat cancer?
Can I tell it from turkey tail by looking?
No. Wild fungi cannot be safely identified from text, photos or an app, and look-alikes are common. Ask a trained local expert.
Does it interact with medicines?
Unknown. No interaction study or case report was found. Ask a pharmacist before using any medicinal fungus.
Can I buy a false turkey tail supplement?
We found no product. Check the Latin name on any turkey tail product (real turkey tail is Trametes versicolor), and for mushroom supplements in general NCI says label contents are not guaranteed.
