That time hasn't arrived yet, but it won't be long. Check those dogwood trees. If you have never seen a morel before, it is probably best to get someone who has to identify your first finds. Although morels are very distinctive are hard to mistake for something else, there is one fungus called the false morel that is toxic. Some people get sick after eating this variety.
False morels look most like the early black morel.
There are some fungus identification books around, and books with photos of morels can give you a very good idea of what to you're hunting. However, there is no substitute for experience. The best bet is to get someone who knows morels to take you hunting. Once you have seen a few in their natural habitat, you will never forget their appearance. Most morel fans slice them lengthwise into two pieces.
