I nearly stepped on a bird’s nest filled with tiny eggs recently. Thankfully, the miniature wonder was actually a delightful mushroom known as bird’s nest fungi (of the Nidulariaceae family). 

Closer inspection revealed a grouping of cup-like structures (peridia) cradling egg-shaped spore capsules (peridioles). The captivating cluster brought to mind a landscape well suited for fairies or other forest nymphs. 

The world of fungi is quite fascinating and full of fantastical and varied expressions with helpful functions. Bird’s nest fungi, for example, are saprobes (decomposers that break down dead organic matter). They derive nourishment from decaying wood or plant matter and can often be seen nestled throughout wood chips or garden mulch.

“Fungi are the grand recyclers of our planet, the mycomagicians disassembling large organic molecules into simpler forms, which in turn nourish other members of the ecological community,” explains the renowned mycologist and author Paul Stamets.

Raindrops play a surprisingly important role in helping this unique mushroom to spread its spores. As described by David Arora in his comprehensive field guide, “Mushrooms Demystified,” the force of a single raindrop will splash the eggs out of the nest, propelling them upward and outward, thereby earning them the nickname “splash-cups.”

These dainty mushrooms are completely harmless to people, pets or plants and are particularly delightful to behold. Grab a magnifying glass and get down on the ground to explore the world of wonder at your feet. And keep watch for a fetching fairy in the fall foliage.
