Common Names: Yellow fairy cups, lemon discos
Sub-category: Cup Fungus
Fruit bodies begin as spherical, closed globules, before expanding. The smooth, bright yellow fruit bodies are small, typically less than 3 mm in diameter and up to 1 mm high, and shallowly cup- or disc-shaped. The inner surface is smooth, and bright yellow, while the outer surface is a paler yellow. In mass, the spore color is white. The stalk is broad, pale yellow in color, and short to nearly absent; when present it is rarely more than 1 mm. The fruit bodies may be so numerous that their shapes are distorted by overcrowding. Fruit bodies that have dried are wrinkled and have a dull orangish-brown color. Grows in dense clusters on decaying deciduous wood that has lost its bark in late summer and autumn.
