Agaricus Blazei vs White Button can look like the same mushroom listed twice. They share the genus Agaricus, but white button is Agaricus bisporus. The commercial name Agaricus blazei has a different history, associated with Agaricus subrufescens. That is why we keep both full names on our ingredient list.
The shared word “Agaricus” does not mean they are the same
Agaricus is the genus name. The second word distinguishes the species, so two ingredients can begin with “Agaricus” without being duplicates.
In his 2005 taxonomic study, Richard W. Kerrigan used DNA and mating evidence to identify the cultivated Brazilian isolates studied as A. subrufescens. This explains the commercial blazei/subrufescens connection for that material, but does not authenticate every retail batch sold as “blazei.”
Agaricus Blazei vs White Button comparison chart
The mushroom comparison chart below keeps the commercial and scientific names separate.
| Question | Agaricus blazei, as commonly marketed | White button |
|---|---|---|
| What does the name tell you? | A commercial identity that may require species clarification | A familiar culinary name for A. bisporus |
| Useful scientific context | A. subrufescens for the cultivated material studied by Kerrigan | A. bisporus |
| Is it a growth stage of white button? | No basis for treating it that way | White button is a market form of A. bisporus |
| First product check | Supplier identification, material, and preparation | Food preparation or product form, depending on the item |
| Main error to avoid | Rewriting every “blazei” entry as an authenticated modern species | Treating every Agaricus ingredient as white button |
Why you may see both “blazei” and “subrufescens”
You may see “Agaricus blazei” on a product and “Agaricus subrufescens” in research about it. Record the label’s wording and use product-specific documentation if you need to match the ingredient to a study.
White button, cremini, and portobello: the familiar group
Mushroom Council identifies white button as Agaricus bisporus. Cremini and portobello are market forms of the same species; mushroom-spawn producer Amycel documents brown A. bisporus strains used in production.
These market forms do not mean that every white button simply turns brown as it ages. They also do not make other members of Agaricus white button mushrooms.
What the ingredient list tells you
In a functional mushroom comparison, ingredient identity, serving amount, and health evidence answer different questions:
| Claim | What would support it | What does not support it by itself |
|---|---|---|
| The name appears in the formula | Current public label or product listing | A study on another product |
| The ingredient has a specific identity | Relevant supplier or batch documentation | The commercial name alone |
| A serving contains a specific amount | An individually disclosed per-serving amount | Dividing a blend total by the ingredient count |
| The product has a health outcome | Evidence on the relevant product or preparation and outcome | Taxonomy or a longer ingredient list |
We list Agaricus Blazei and White Button separately in our formula. Their shared genus does not tell you their amounts or establish a combined effect.
When comparing types of mushrooms in mushroom coffee, check the rest of the formula as well. A mushroom blend total does not tell you each ingredient’s share; use an individually stated amount when your decision depends on one.
Are you choosing food, a powder, or a drink?
- For cooking, use a culinary ingredient intended for the recipe. Supplement powder is not a direct substitute for sliced white button.
- When reading a label, keep both full names and any stated amounts.
- For nutrition, compare the same preparation and portion size.
- For research, match the organism, preparation, amount, population, and outcome.
For dinner, choose the food ingredient the recipe needs. For coffee, compare a formula you understand and a preparation you will use. An unfamiliar name alone is not a reason to prefer a product.

Frequently asked questions
Is Agaricus blazei just another name for white button mushroom?
No. White button is Agaricus bisporus. The commercial blazei name has a different naming history, and the shared genus does not make the ingredients interchangeable. Keep the complete names whenever a recipe, label, or study distinguishes them.
Why do some Agaricus blazei products also mention Agaricus subrufescens?
The overlap reflects a history of identification and commercial usage. Kerrigan’s 2005 study placed the Brazilian cultivated material examined in A. subrufescens. That helps explain the naming connection, but a seller still needs product-relevant support for the identity it claims.
Does a blend listing Agaricus Blazei and White Button contain the same mushroom twice?
No, the shared genus name is not a reason to count them as the same ingredient. We list Agaricus Blazei and White Button separately in our formula. White button is associated with A. bisporus; the blazei name has the different naming history explained above.
Can Agaricus blazei powder replace white button mushrooms in a recipe?
Check whether the powder is intended as a culinary ingredient, an extract, or a finished supplement. For a recipe requiring sliced white button, use a food product intended for cooking. There is no direct serving conversion from supplement powder to whole mushroom pieces.
Is Agaricus blazei healthier than white button, or just less familiar?
A less familiar name is not evidence of better nutrition or a stronger effect. Food comparisons need matched servings and preparation states; health claims need evidence on the relevant material and outcome. The taxonomy cited here answers an identity question, not a health ranking.
