A pale-brown to brown cup fungus found on the ground in woods, typically where woody debris has accumulated. It is one of many similar brown Peziza species and usually needs microscopy for a confident identification. Long known in field guides as Peziza sylvestris.
Edibility unknown. Not a food species; brown cups are hard to identify and should not be eaten.
