A medium to large brown cup fungus of spring and early summer that often turns up while people are hunting morels. Cups are reddish to purplish or olive brown and often pinched or contorted when clustered. It was moved from Peziza to the new genus Phylloscypha in 2020.
Edibility disputed; not recommended. Some European authors list it as edible while others call it unknown. Brown spring cups can be confused with cup-shaped Discina species (formerly in Gyromitra), relatives of the false morels that may contain gyromitrin.
