Most people have little concept of how to distinguish real cordyceps from fake ones, especially newcomers who urgently need cordyceps, as their knowledge about cordyceps is very limited. Some travelers to Qinghai-Tibet and Yunnan also encounter many people selling cordyceps, and getting scammed happens frequently.
The source describes Chinese caterpillar fungus as having both insect and plant-like features and names four 'miraculous' components: cordycepin, cordycepic acid, cordyceps polysaccharides and superoxide dismutase. It provides no scientific evidence for the label 'miraculous,' which is not a scientific classification.
Not Every Cordyceps Fungus Is Chinese Caterpillar Fungus
The source says about 570 cordyceps varieties had been identified and that only one is Chinese caterpillar fungus. It warns that other species are passed off as the genuine product, naming Yaxiangbang cordyceps as especially difficult to distinguish and claiming it has some toxicity. These taxonomy and toxicity statements are preserved as source claims; visual comparison alone cannot guarantee safety or authenticity.
Cordyceps Fungi ≠ Chinese Caterpillar Fungus
Chinese caterpillar fungus belongs to the wider group of insect-parasitic cordyceps fungi, but the general term does not always mean this particular product. The source cites more than 15,000 fungi in a 'Fungal Catalogue' while saying Chinese caterpillar fungus is one species. It adds that modern pharmacological research has examined medicinal value in many cordyceps fungi, but their trace constituents differ and the products are not interchangeable. The counts and efficacy statements are source claims, not medical advice.
Steps to distinguish genuine and counterfeit cordyceps
Step 1: Look at the stroma
The stroma is the 'grass-like' fruiting body growing from the insect. The source says genuine specimens have a small spoon-shaped tip, while some counterfeits have a mushroom-like tip. It also describes fakes made from flour paste shaped in a mould, fitted with fern-root or other false fruiting bodies and then dyed.

Step 2: Look at the insect body
Genuine cordyceps have eight pairs of legs, with the four middle pairs very obvious. Fake cordyceps vary in the number of insect legs due to different types of larvae.
The body of genuine cordyceps has ring patterns, with three rings per group, arranged in series. The rings near the head are finer. Fake cordyceps, on the other hand, have symmetrical raised dots on one side, with parallel stripes of equal spacing, generally made with a mold.
Step 3: Look at the cross-section
When broken open, genuine cordyceps show clear patterns, with a cross-section color of yellowish-white or white, and a black-brown gland shaped like a 'V' or 'W'.
Step 4: Look at the color, avoid alum cordyceps
The source describes Chinese caterpillar fungus as brownish yellow to brown with a relatively even colour. Yaxiangbang cordyceps is described as greyish white with dark-brown spots on the back, especially after drying, although dyeing may make it look similar to the genuine product.
The source warns that some sellers coat cordyceps with alum solution to increase its dried weight. It claims long-term consumption can impair calcium and iron absorption, cause anaemia or osteoporosis and, in severe cases, affect nerve-cell development. These are source health claims, not medical advice.
The source says alum-treated cordyceps may show a milky-white surface powder and have a sour, astringent taste, while genuine specimens have a light grassy aroma. Although the original suggests touching it to the tongue, unknown or adulterated products should not be tasted as an identification test.
Step 5: Smell the aroma, avoid sulfur-smoked cordyceps
When cordyceps is opened, it has a strong earthy aroma similar to straw mushrooms or shiitake mushrooms. Dyed Axiang stick cordyceps may look very similar in color to winter cordyceps, but its scent may change, possibly smelling like fish, low-quality perfume, or chemical materials.
If cordyceps is moldy, smoking it with sulfur can make it appear like fresh, high-quality cordyceps again. A simple way to identify sulfur-smoked cordyceps is to smell it—sulfur has a pungent odor, unlike the unique grassy aroma of cordyceps. When selecting cordyceps, do not focus solely on superficial appearance.
Step 6: Test the hand feel, avoid artificially cultivated cordyceps
The source suggests lifting a handful to compare weight and texture: properly dried genuine specimens are described as light and crisp like dry grass. It says pressed imitations may be recognised by comparison with normal features or by soaking, but these checks do not by themselves prove authenticity.

In addition, rub or wipe the real cordyceps' larva and stromata separately in your hands; your hands will not get stained, nor will they stick to any powdery substances other than sand or wood debris. If your hands get stained or have unusual powder, it is fake cordyceps.
Artificially cultivated cordyceps: the heads of artificial cordyceps curve, and the part near the eyes becomes thinner and sharper, while wild cordyceps heads do not curve or sharpen. The body is smooth and the color is consistent. At the same specification, artificial cordyceps is much lighter than wild cordyceps.
Step 7: Source-Described Taste and Texture
The source describes genuine cordyceps as becoming soft and increasingly aromatic when chewed, like fresh green soybeans, while counterfeits are said to feel hard or gritty and develop a strong earthy taste when moistened. This description is preserved from the source, but unknown specimens should not be tasted to establish authenticity.
Step 8: Check for Toothpicks or Wire
The source distinguishes lower-grade genuine cordyceps from adulterated products and reports cases in which thin metal wire was inserted into the insect body to increase weight. Such pieces may feel unusually heavy, with the wire visible when a specimen is broken open.
Cordyceps can break during harvesting, and collectors may rejoin the pieces with a toothpick before selling them at the lower broken-piece grade. The source also warns that some sellers thread broken pieces with toothpicks or wire to improve appearance and add weight, creating a risk of mouth injury if consumed.

Cordyceps pricing questions
Q: How do cordyceps from Nagqu in Tibet, Yushu in Qinghai and Ganzi in Sichuan differ?
A: The source ranks origins as Nagqu (above 4,500 metres, top tier) > Yushu (strong value for money) > Ganzi (lower altitude, medium quality). It says all three look similar and require specialist appraisal. This hierarchy is a source market view, not an independent guarantee of origin or quality.
Q: How do you distinguish real cordyceps?
A: The source's checklist describes 8 pairs of legs with the middle 4 more prominent, a fruiting body growing from the centre of the head, a mushroom-like aroma and a pale yellowish-white interior when broken. It warns about flour-paste and moulded imitations. These signs support screening but do not prove authenticity.
Q: How is cordyceps graded by count?
A: Grades are expressed as pieces per catty. The source says a lower count means larger, scarcer pieces: 2,000 pieces per catty is top grade, 3,000–4,000 is mid-to-high grade, and 5,000–6,000 is the general-market grade. Fewer pieces per catty generally means a higher unit price.
Q: How to store cordyceps best?
A: Use a sealed glass jar with food-grade desiccant and store it in a cool, dry place away from light. The source recommends airing it for 1 day every 6 months and claims quality remains stable for 5–8 years, with constituents declining after 10 years. These timeframes are source guidance, not a product-specific guarantee.
Q: How can I request an appraisal for unused cordyceps at home?
A: Send overall and close-up photos of the fruiting body and insect body via WhatsApp to 69035182. The source states that a preliminary estimate is returned within 30 minutes.
