Gyromitra korfii f. cul. innocuus · quasi-gyromitrinica-solubilis-fickeana-volatilis

innocuus: The published record carries no link to a toxic molecule: neither a poisoning report nor an assay has identified anything in this species that a kitchen would need to remove. Because the source of that record is the field-guide literature, the listing carries a positive claim as well -- a substantial community base of people who eat it, a widespread cultural record of edibility that comes down to us via field guides. That record is a simplification of what had been more widespread practice prior to global urbanization: silence in it understates practice and is never evidence against a species. Cook it, as nearly every mushroom is cooked -- but the cooking rescues nothing and nothing is being driven out. ⚠ The operation may be physically identical to a detoxification leach: the chanterelle is scalded several times and the water discarded, for bitterness. Nothing in the act distinguishes them and only the REASON does. This name is where that reason lives.

Notes

As post-DNA taxonomy can make it impossible to identify mushrooms in the field to the species level, we advise cooking all mushrooms in the genus as if they had gyromitrin.
