Portobello/Crimini Mushrooms

The popular large stuffing mushroom, and hamburger mushroom. Pick them before the cap opens for Criminis, and after it opens for Portabellas. Either way, you get flavor and freshness that you just can't get from the store. Enjoy in a wide range of preparations.

Portobellos have been used as replacements for hamburger patties by vegans, and as a replacement for the bun by low-carbers, but it is useful in the kitchen beyond that. They are large mushrooms with good protein content, so you can use them creatively to build an entire meal around.

Easy to grow. In fact, the easiest of all commercial mushrooms. If you can't get anything to grow, you can produce these large and tasty mushrooms. Not recommended for cottage industry though as a mono-crop - the only way you can sell these at a profit is if you have a specialty product that uses them, or if you sell them with many other mushroom products.

Good for sheep and pigs, and can help reduce the effects of chemicals in commercial feeds. They may also help protect them from common minor infections.

For people, they contain components that may help reduce damage to skin and eyes from exposure to airborne chemicals.

Currently, these mushrooms are grown primarily from the brown form of Agaricus Bisporus.

Certain seasons of the year, growers may use Agaricus Brunnescens instead of A. Bisporus. A. Brunnescens has a firmer and whiter cap, and pinker (paler) gills when it is young. A. Bisporus is not quite as firm, and the gills turn darker much earlier.

Both Agaricus Bisporus and Agaricus Brunnescens are available in our Mushroom Store.


Mushrooms may cause allergic reactions in sensitive people. Some mushrooms are more likely to do this than others. Please research possible reactions prior to purchase. We are not responsible for how you choose to use our products, and do not claim that mushrooms are completely safe to consume. We merely assure that they are as represented on our website.

We do not make any promises as to the efficacy of any mushroom product to treat or prevent any disease or condition. Please consult a doctor or alternative practitioner prior to using any mushroom product for treatment of any disease or illness.

We cannot guarantee that any spawn, spore, or kit product will grow or produce mushrooms. We do guarantee that our products are as described, and that the methods in our instructions do produce good results, but once our products leave our facility, we can no longer control the factors which are responsible for success. Gardening of any kind is a chancy business, and success depends upon adherence to instructions, and may be influenced by weather, environmental factors, and other controllable and non-controllable factors. As such, we cannot guarantee your success, and advise that if you are uncomfortable with purchasing under these terms, that you refrain from purchase.

We do promise to answer your questions, and offer reasonable assistance if needed, and to correct any errors if a mistake is made on our part.
