FungiAtlas is an online mushroom guide and community resource for people interested in exploring and identifying fungi. Its atlas features profiles of edible, inedible, poisonous, medicinal, and psychoactive mushrooms, with photographs, facts, habitat information, and identification tips. Visitors can browse species by category or through an A–Z directory, and use the photo-based Mushroom ID tool to seek help recognizing wild fungi.

The site also offers a mushroom calendar, moon-phase information, a map covering foraging rules, seasons, and edible species in more than 110 countries, recipes, articles, and community discussions. Popular species profiles include chanterelles, porcini, fly agaric, chaga, and death cap. FungiAtlas emphasizes that mushroom edibility classifications can vary by region and source, and encourages users to verify identifications carefully and never eat a wild mushroom unless they are certain of its identity.

The site’s informational content is free to access. It also features recommendations for foraging gear and books, with qualifying-purchase affiliate links, and invites visitors to connect with the community or support the site through donations
