The poisonous false morels (various species of Gyromitra
) as well as the not-recommended Verpa bohemica
differ in that the cap and stem do not form a single, continuous, hollow chamber. All true morels (species of Morchella
) are edible when properly cooked. A number of other true morels can have a similar appearance, and are sometimes difficult to differentiate in the field, but do not generally match all the key characteristics.
