Organic Button Mushroom, brown - Agaricus bisporus - Pure Culture

Synonyms: brown portobello, brown champignon mushroom 

The champignon mushroom is the most widely cultivated edible fungus worldwide. This creamy to brown agaric or portobello corresponds to the original form with a slightly nutty flavor. The white variation only emerged through a mutation. The albino variant has a less pronounced taste but is now more widespread than the creamy mushroom. It is found in temperate climates across the entire northern hemisphere. In Europe alone, over 40 wild species are knows. Champignons are dung inhabitants and can be found from May to November, especially in cow pastures or compost heaps, under suitable weather conditions.

You receive living, actively growing, axenic cell culture, entirely free of other strains or contaminating organisms, for further propagation. Our pure cultures are custom-made and produced freshly after ordering - in a class 100 clean room environment on a solid nutrient medium (MEA) based on plant-derived raw materials. The culture needs around 2 - 3 weeks until its mature enough for shipping. The culture is supplied in special cell culture flasks (Filling volume: 15 ml culture medium, Growth area: 25 cm², Measurements: L x W x H = 79,7 x 42,6 x 26,53 mm) with breathable, hydrophobic membrane. This special design prevents introduction of contaminants and enables optimum gas exchange thanks to the high air flow rate of the membrane. With this packaging, the mushroom culture can withstand longer shipping distances and time without compromising quality or germination ability. 

This product is intended for the professional production of grain spawn to further propagate this strain of fungi. Working with pure cell cultures requires detailed mushroom cultivation skills. For beginners and hobby growers we recommend starting with grain spawn or sawdust spawn.
