Morchellaceae: True Morels and the Hollow Test
Morels are among the most sought wild edibles. Their family also teaches the two habits that keep morel foragers safe: the lengthwise cut and thorough cooking.
Caution
What Defines Morchellaceae
True morels, genus Morchella, have a pitted cap that looks like a honeycomb, and its pits and ridges sit directly on the cap. Cut one lengthwise and it is completely hollow, one clean chamber from the tip of the cap to the base of the stem. Every member on this page shares that open interior.
The members vary the outward pattern. Black morel has mostly vertical ridges that darken with age, and its cap meets the pale stem at a shallow groove. The cap of the half-free morel joins partway down a long hollow stem, while Verpa caps hang from the very top, so you check the attachment point as its own step.
The Hollow Test
The hollow test is the fastest way to separate a true morel from a dangerous false morel. True morels are empty inside. False morels have chambers, wisps or cotton-like stuffing inside. You can see both cuts next to each other in false morel versus morel.
Why Do Morels Need Cooking?
Raw or undercooked morels upset the stomach even when you have named them correctly. Cook them thoroughly before anyone eats them. That rule holds for every species in the family, and the page on eating morels raw describes the illness.
Warning
Never eat a morel raw, and never trust a morel that is not hollow inside. Confusing it with a false morel can be fatal.
When Do Morels Come Up?
Morels are a spring mushroom, often near ash, elm and old apple trees, and in the year after a burn. They vanish as the soil warms, so the window is short. Timing shifts from place to place, and the morel season map by state shows when the run usually starts near you.
Frequently Asked Questions
Are morels safe to eat raw?
No. Even correctly named morels cause stomach upset when raw or undercooked. Always cook them thoroughly.
How do I tell a true morel from a false morel?
Cut it lengthwise. True morels are completely hollow, with one open chamber. False morels have chambers, cotton or stuffing inside, and their caps look brain-like instead of pitted.
When do morels fruit?
Morels fruit in spring, usually as the ground warms after the first mild rains. They favor ash, elm and old orchards, and often appear the year after a fire.
