Definition

Noun: A species of fungus in the family Discinaceae, commonly known as the "false morel." It is characterized by a reddish-brown, brain-like or convoluted cap. While it is considered a choice edible mushroom in some regions after proper preparation, it contains the toxin gyromitrin, which can be deadly if the mushroom is consumed raw or improperly processed.

Usage Examples

Notes on Meaning

This term has a specific scientific/technical meaning. In everyday conversation, foragers and cooks would more commonly use the term "false morel," reserving Gyromitra esculenta for precise identification. Its meaning embodies a paradox: its scientific name suggests edibility ("esculenta"), while its biological reality is defined by significant toxicity.

Noun

1. a poisonous gyromitra; the surface of the fertile body is smooth at first and becomes progressively undulating and wrinkled (but never truly pitted); color varies from dull yellow to brown
