Helvella costifera is a species of fungus in the family Helvellaceae. It produces distinctive cup-shaped fruiting bodies supported by a ribbed stalk. The fungus features greyish to greyish-brown caps with prominent yellowish-white ribs that extend from the hollow stalk and branch into forks on the cup's undersurface. First described scientifically in 1953, H. costifera has a widespread distribution across Europe, Asia, and North America, including China, Spain, Scandinavia, and Mexico.
