Nidula candida (woolly birdsnest fungi)
They are very small cup-like structures which look like a tiny bird's nest covered by a thin skin or lid. When this lid peels back, you can see things that look like eggs, but they are actually little bundles (peridioles) of compressed spores.
These are covered with a sticky substance so that when they are splashed out by rain drops, they stick to the the suface they land on. The furry (woolly) covering of these fungi makes it easily distinguishable. Original public domain image from Flickr
