A tiny, greenish-yellow cup fungus common on cow and other herbivore dung. As the large asci mature they push above the disc surface, so the disc looks peppered with black-purple dots from the dark spores inside. It is one of the commonest dung fungi.
Not edible: far too small to be food. California Fungi lists its edibility as unknown.
