Bird's Nest Fungi

Crucibulum vulgare, a species of bird’s-nest fungi, forms egg-shaped basidiocarps and is a member of the phylum Basidiomycota. Besides being cute, the shape of the bird's nest is actually functional! The nest acts as a splash cup. When raindrops fall into the cup, the eggs are splashed out some distance away from the nest. If they land on a suitable substrate, they will germinate and form new mycelium that can grow into new fruiting bodies.
