Morels are easy to identify, but you still have to know what they look like and how to tell the real thing from false morels. Real morels are hollow, and their caps are attached to the stem at the bottom. The caps have pits all over. The mushroom that most resembles the morel, the verpa, has ridges, not pits, and the cap isn’t attached at the bottom. You can see a sort of skirt along the bottom edge instead. The other false morels are big, non-symmetrical, and clearly ridged. Avoid the verpas and false morels, which are, at the least, not tasty and, at the worst, toxic enough to make you sick.
