Welcome to Mushroom World, your resource for mushroom information. This site contains information and images of mushrooms found mainly in Europe and North America.
Many mushrooms are poisonous and some are lethally poisonous. It can be very hard to distinguish between an edible and a poisonous mushroom. We recommend, because of this, that you don't eat wild mushrooms at all, and this site does not contain any information about the edibility or toxicity of the mushrooms listed here.
There are thousands of different mushroom species, so we have tried to limit those we list to the most common ones. New species are also continuously added to the site.
If you know the characteristics of a mushroom, but need help to identify it, try our Mushroom identification helper. You can browse mushroom pictures there and perhaps find a match.
If this site cannot help you, we recommend mushroomobserver.org, which is a community site for mushroom identifications. There are also many Facebook groups for mushroom identifications like the Mushroom Identification - public group.
We have also created a quiz where you can test how good you are at identifying fungi. You can repeat the quiz as many times as you want, each time with new questions.
