Mushroom Observer is a citizen science website where users record observations about mushrooms, help people identify mushrooms they aren’t familiar with, and expand the community around the scientific exploration of mushrooms (mycology). The site’s emphasis is on large fleshy fungi, however other fungi such as lichens, rust and molds as well as fungus-like organisms such as slime-molds are also welcome.
