North American Mushroom Clubs
Mushroom clubs offer fellowship and instruction, helping mushroomers of all levels learn their local mushrooms. Most clubs host regular walks during the mushroom season, publish a newsletter, and have sit-down meetings with presentations on fungal topics. Other common club activities and events include an annual weekend foray and/or mushroom fair. See their websites for contact info and more details.
