A great article in USA Today – How to Find Morel Mushrooms in Ohio State Parks!!!
According to Ohio State University Extension, there are more than 2,000 kinds of wild mushrooms that grow in the state. Of these, the morel is one of the first that you can collect in spring. The morel, which is also called the sponge mushroom because of its spongy cap, are most abundant from the first part of April to the first part of May in many Ohio State Parks. You must take great care when hunting morels, because there are some poisonous mushrooms, such as the false morel, that grow in the same conditions and look similar.
