Crucibulum laeve

Crucibulum is a genus in the Nidulariaceae, a family of fungi whose fruiting bodies resemble tiny egg-filled bird's nests. Often called "splash cups", the fruiting bodies are adapted for spore dispersal by using the kinetic energy of falling drops of rain. The "eggs" inside the bird's nests (technically known as peridioles) are hard waxy shells containing spores, and tend to stick to whatever nearby herbage they land on, thus increasing the odds of being consumed and dispersed by herbivorous animals. Members of this genus are saprobic, obtaining nutrients from dead organic matter, and are typically found growing on decayed wood and wood debris. The three known Crucibulum species (C. laeve, C. parvulum, and C. cyathiforme) are distinguished from other genera of the Nidulariaceae by their relatively simple funiculus – a cord of hyphae that connects the peridiole (the "eggs") to the exterior of the bird's nest.
