Organic Button mushroom, brown - Agaricus bisporus - Grain spawn
Synonyms: Champignon mushroom, Portobello mushroom
The button mushroom is the most commonly cultivated edible mushroom in the world. This cream-coloured to brown Egerling or Portobello corresponds to the original form with a slightly nutty flavour. The white button mushroom was only created through a mutation. This albino variety has a less pronounced flavour, but is now more widespread than the cream-coloured mushroom.
It is found in temperate climate zones throughout the northern hemisphere. In Europe alone, over 40 species are known to grow in the wild. Mushrooms are dung dwellers and can be found in suitable weather conditions from May to November, especially in cow pastures or compost heaps.
