Vinegar cup
A deep, brown cup fungus on a short, cream-colored stem whose prominent branching ribs extend up the outside of the cup almost to the rim. The inner spore-bearing surface is brown and smooth to slightly wavy. It grows on sandy soil under conifers and hardwoods, mainly in spring and summer.
Not recommended; Roger Phillips lists it as poisonous. Related Helvellaceae are reported to contain monomethylhydrazine (gyromitrin-type) toxins, and its edibility is otherwise unknown (Wikipedia).
