False MorelGyromitra esculenta

☠️ Deadly

True morels have HONEYCOMB-PITTED caps and are HOLLOW end-to-end. False morels (Gyromitra) have BRAIN-LIKE WRINKLED caps and are SOLID or chambered inside. Gyromitra contains MMH — potentially lethal even after cooking.

Half-Free MorelMorchella punctipes

✓ Both edible

Both are edible, but the half-free has a cap only attached HALFWAY down the stem (lift the cap skirt to check). Cook both thoroughly.
