If you don't know this you should. Pinch or cut only.The morel is just the fruit of the mushroom attached to a fine web structure (mycelium) that could possibly be blocks wide and long, some suggest even miles. When you pull a morel out of the ground you damage the structure of the morel plant called the mycelium. The morel plant usually has a symbiotic relationship with the elm or ash or whatever tree it attaches to, and when the tree is stressed, ie dying, it sends out the morels to shoot spore to re populate itself. Never pluck, always cut or pinch.
