Crucibulum laeve White-Egg Bird's Nest
Picture shows various stages in development. Some of the young fruitbodies still have the lids that protect the developing peridioles (=eggs). Some fruitbodies are filled with mature peridioles. A few fruitbodies are empty or nearly so (top centre) where the rain as splashed the peridioles out of the nests. New fruitbodies are sometimes deveoping inside the shells of old fruitbodies.
