Cordyceps products can be made from the fruiting body, from mycelium, or from an extract of either. The difference matters because it changes what is actually in the jar. Here is how to tell them apart.
Two parts of the same fungus
- Mycelium: the thread-like, vegetative network that grows through the substrate and absorbs nutrients.
- Fruiting body: the structure the fungus produces to release spores. In Cordyceps militaris these are the bright orange, finger-like strands.
When C. militaris is cultivated, mycelium first colonises the substrate in the dark; light then triggers the fruiting bodies to grow up from it.1
How mycelium products are made
Some products are made by growing mycelium on grain and then drying and milling the whole mass. Because the mycelium is woven through the grain, the finished powder contains both fungus and leftover substrate. Other mycelium products are grown in liquid fermenters and filtered out. How much substrate ends up in a product depends on the manufacturer, so look for the part used on the label and, where available, analytical information.
How fruiting body products are made
With C. militaris, the fruiting bodies grow above the substrate and can be cut off and dried on their own. They can then be sold whole, ground into powder, or extracted with water and/or food-grade alcohol.
Comparing the two
| Fruiting body | Mycelium on grain | |
|---|---|---|
| What it is | Harvested orange strands | Mycelium dried together with its growing grain |
| Easy to identify? | Yes, when sold whole | No, it is a powder |
| May contain substrate | No | Yes, in varying amounts |
| Compound levels | Vary with strain and growing conditions1 | Vary with strain, process and substrate share |
Reading a label
- Look for the species (Cordyceps militaris or Ophiocordyceps sinensis).
- Look for the part: "fruiting body", "mycelium", or "extract of …".
- For extracts, check the solvent and ratio (for example 1:5).
- Check the FSSAI number and the maker's address.
What Cordygen uses
All Cordygen products are made from cultivated C. militaris fruiting bodies. Cordygen Raw is the whole dried fruiting body — you can see the intact strands in the glass jar. Vital Capsules and the Tincture use fruiting-body extract. For more on extracts, read fruiting body vs extract, or start with our Cordyceps militaris guide.

How to tell what you are actually buying
The difference is not academic — it is printed on labels, if you know where to look. Use these checks on any Cordyceps product, including ours:
Read the ingredient line first. A fruiting-body product says so in plain words: "Cordyceps militaris fruiting body". Vague lines — "Cordyceps powder", "Cordyceps blend", or the giveaway phrase "myceliated grain" / "mycelial biomass" — mean you are mostly buying the grain the mycelium grew on.
Do the capsule maths. A 500 mg capsule of myceliated grain may contain well under half fungus by weight, because the grain is ground in with it. A fruiting-body capsule or a whole dried jar has nowhere to hide: open a jar of Cordygen Raw and you are looking at the mushrooms themselves.
Be careful with "full spectrum". The phrase sounds premium and sometimes means "everything, including the substrate". Ask a harder question instead: which part, how much of it, and what does the label guarantee? Our labels answer with numbers — for Raw, per 100 g: 28.6 g protein, 5.8 g natural beta-glucans and cordycepin of approximately >0.1 g.
Does mycelium have any value at all?
Honestly, yes — mycelium is real fungus tissue and contains some of the same classes of compounds. The problem is not that mycelium is worthless; it is dilution and disclosure. When mycelium is sold still mixed with its growth grain, nobody — including the seller — can tell you how much fungus you are getting per serving, and the compounds people buy Cordyceps for, cordycepin in particular, are concentrated in the fruiting body. That is why the fruiting body takes weeks of controlled growth and careful harvesting, and why it costs more: our price guide shows the per-day maths across formats.
Cordygen's position is simple enough to print on a jar: Raw is 100% fruiting body, the capsules and tincture are extracts of the same cultivated militaris, and nothing is padded with grain. If you are comparing us with another brand, the comparison to demand is this one — part for part, gram for gram.
