Those magic mushrooms grow in Ireland. They sprout in cow pies. If you eat them you will see leprechauns. After you eat the mushrooms the leprechauns will come right up to you and talk to you.
Who wants to eat a cow pie to see leprechauns????.........
They grow in American cow poop as well. But some of the feed companies have introduced spore blockers to prevent the production. You used to could sneak onto a dairy farm in the spring and pick a pound of them I hear.
Here fungicides in livestock feed have about eradicated them in the states except the forest species
