The birdnest fungi 2 by Steve Axford. a tiny cup-shaped fungus containing minute flattened spheres resembling eggs in a bird's nest. It is the reproductive or fruiting body of a remarkable fungus known in scientific circles as Cyathus olla.
Nidulariaceae are also called Bird's Nest Fungi for obvious reasons. Those little egg-looking things inside are actually spores. The fungus will wait for the perfect opportunity to launch these into the air.
