California False Morel is a mushroom that is commonly found in the western part of North America. It is known by many names, such as the Half-free Morel, Early Morel, or the Smooth Head Morel. The California False Morel is often mistaken for the true Morel, but it is poisonous and can cause serious illness if eaten. The mushroom has a unique appearance, with a honeycomb-like cap and a brown, wrinkled stalk. Some other synonyms for this mushroom include the Verpa Mushroom, Thimble Morel, and Gyromitra Mushroom. It is important to be cautious when identifying mushrooms in the wild, as some can be deadly if ingested.
