Eastern half-free morel
The eastern half-free morel, Morchella punctipes, is a wild morel of eastern North American forests that is eaten after cooking. Raw or undercooked morels can cause serious poisoning.
A morel of forest and woodland
Morchella punctipes is recorded in the catalogue as a culinary morel of eastern North America. It grows in forest and woodland, and its ecology depends on its lineage. The catalogue lists its supply as wild.
The catalogue notes that true-morel taxonomy often requires molecular confirmation, so the species limit of this name is not settled by a field description alone.

Cooking is required
The catalogue records the use as a culinary morel and states that cooking is required. It warns that raw or undercooked morels can cause serious poisoning.
A 2023 outbreak in Bozeman, Montana, linked to morels served partly cooked or raw, is described in the CDC's account of the outbreak. Of 51 people who reported gastrointestinal illness, two died. The CDC report found that eating raw morels was more strongly associated with illness than eating cooked or partially cooked morels, and recommends cooking morels before eating them. The outbreak was linked to morels generally, and the report does not establish a safety margin for any species in particular.

Identification and limits of safety
The catalogue states that cooking mitigates risk but cannot be treated as an absolute safety guarantee. A misidentified false morel is not made safe by cooking, and this page gives no field identification guide for this species.
Anyone gathering morels should confirm the identification with an experienced expert before eating any of them.
