Blonde morel

What it is

Blonde morel is the common name the catalogue uses for Morchella tridentina, a wild true morel. True morels have a sponge-like cap of pits and ridges on a hollow stem, and the cap is attached to the stem at its base. The catalogue records the scientific name as a research label rather than a reconciled accepted name, so a collection named this way should be checked against current taxonomy before it is identified as this species.

Morphology alone may not settle which morel a collection is. Several Morchella species look alike in the field, and the catalogue notes that the species name needs confirmation for individual records.

Where it is gathered

The catalogue places the food-use record in Patagonia and describes the fungus as wild-harvested and traded regionally. It grows in forest, and the catalogue notes that its ecology varies between lineages of the genus.

The sources do not give local names, seasons, quantities or prices for this species, so the page does not state them.

Safety when eating morels

Morels must be cooked before eating and must not be eaten raw. In a 2023 outbreak in Bozeman, Montana, 51 people reported gastrointestinal illness after eating a sushi roll containing morels, and three were hospitalized; two deaths are reported. Investigators identified morels as the likely source. The species in that outbreak was Morchella sextelata, not M. tridentina, but the report is the basis for the cooking advice here.

The report found that raw morels were more strongly associated with illness than cooked or partially cooked morels, and that more morels eaten were linked to higher odds of illness. It states that cooking is likely to reduce toxin levels, but it does not say cooking removes all risk, and the toxin involved was not confirmed. A cooked morel is therefore not guaranteed safe.

Notes and gaps

The Patagonian record establishes a food use and a regional trade for the species, but the sources here do not describe a local preparation, a sale point or a dish for this species. Those points are left open rather than filled from other morels.
