Science Buddies: "Ask an Expert"

If I have found a mushroom or have an image of one, how can I find out what species it is?

Hello. Is this for a science fair project? If so, tell us a little more about your project. This forum is to help students with their science fair projects and not to help with homework or other questions.

Thank you

This is for a science fair project where I am seeing if mushrooms can help decrease excess radon in soil. I want to use mushrooms that are common for my area but I don't know how to classify them after I have found them.
