What is "helvella"

n. any fungus of the genus Helvella having the ascocarps stalked or pleated or often in folds

Helvella is a genus of ascomycete fungus of the family Helvellaceae. The mushrooms, commonly known as elfin saddles, are identified by their irregularly shaped caps, fluted stems, and fuzzy undersurfaces. They are found in North America and in Europe. Well known species include the whitish H. crispa and the grey H. lacunosa. They have been reported to cause gastrointestinal symptoms when eaten raw.

The generic name was originally a type of Italian herb but became associated with morels.
