The liberty cap [or Psilocybe semilanceata] is a grassland species strongly associated with grazing livestock, though not growing directly from dung. There is a strong possibility that this mushroom, a common species in temperate Europe, was introduced to Haida Gwaii with livestock and fodder grass species. So this species may not have been available before European settlers and their agriculture became established in Haida Gwaii.
