Comments: Most obvious is its preference for fruiting in clusters on horse dung or decayed straw. While many other cup fungi also occur on dung, these are smaller, differently coloured, or have hairs on the cup margin. Peziza vesiculosa is additionally distinguished by a wrinkled yellowish-brown hymenial inner surface and a pale tan outer surface.
