DSC_2526 Swiss brown, or Portobello mushroom (Agaricus bisporus) a commercial species, probably derived from a wild European mushroom, (Agaricus campestris) but it has evolved further and now has its own scientific name, and a more delicate flavour than wild kinds. It typically matures with a brownish cap, but in 1926, a Pennsylvania mushroom farmer found a clump with white caps and this mutation has become widespread. Dunedin *
