Peziza
The fruit bodies of species of Peziza are fleshy, mostly cup-like in shape and appear on soil. They range from one to 10 centimetres in diameter, though mostly no more than half that. The upper surface is smooth and generally some shade of brown (from very pale yellowish brown to blackish brown) but they may also be a dull violet. The lower side is paler (sometimes a dirty white) and is smooth to rough, but with no hairs or bristles. The fruit bodies may appear in clusters and then, through mutual pressure, are no longer cup-like but quite distorted. Sometimes the cups may flatten out or even fold back a little (e.g. http://www.cpbr.gov.au/fungi/images-captions/peziza-sp-0101.html).
