Here are some swatches of Bisporella citrina the Lemon Disco. Each cup is less than 3mm across, but they can swarm in large enough numbers to be collectively eye-catching despite their tiny size. They grow on well rotted logs of deciduous trees.

Commonly known as Lemon Disco or Yellow fairy cup, Bisporella citrina (Heliotales - Heliotaceae) is a tiny and colorful wood-rotting fungus,  commonly found on dead oaks and other hardwoods.

Citrin - literally means lemon-yellow, but don't let that mislead you, often the fruit bodies are often a bright daffodil yellow.

This ascomycete is found in Britain and Ireland, throughout mainland Europe as well as in many other parts of the world including North America.
