<P> The mushroom also has a widespread distribution in North America . In Canada it has been collected from British Columbia , New Brunswick , Newfoundland , Nova Scotia , Prince Edward Island , Ontario and Quebec . In the United States , it is most common in the Pacific Northwest , west of the Cascade Mountains , where it fruits abundantly in autumn and early winter ; fruiting has also been reported to occur infrequently during spring months . Charles Horton Peck reported the mushroom to occur in New York in the early 20th century , and consequently , much literature published since then has reported the species to be present in the eastern United States . Gaston Guzman later examined Peck 's herbarium specimen , and in his comprehensive 1983 monograph on Psilocybe , concluded that Peck had misidentified it with the species now known as Panaeolina foenisecii . P. semilanceata is much less common in South America , where it has been recorded in Chile . It is also known in Australia ( where it may be an introduced species ) and New Zealand , where it grows in high - altitude grasslands . In 2000 , it was reported from Golaghat , in the Indian state of Assam . </P>
