What You Should Know
Helvella queletii is a species of fungi in the family Helvellaceae of the order Pezizales. The fruit bodies consist of light to dark grayish brown, cup-shaped inner fertile surface, and a paler exterior covered with fibrils. Their margins are distinctly inrolled, especially when young or dry. The fruit bodies are supported by whitish cream, longitudinally furrowed, hollow stalks. It is growing under hardwoods or conifers and is widely distributed in North America.
Helvella solitaria is a synonym and may be the more appropriate name for the species since solitaria predates queletii.
