The tiny, tiny objects at the right are appropriately known as Bird's Nests -- they are members of the Nidulariales. Each of the "nests" is barely large enough to hold a BB. The little black "eggs" in the "nests" (the eggs are technically called "peridioles") are at first covered by white membranes, but at maturity the membranes rupture, exposing the eggs to open air. Then raindrops splash the eggs out of the nest. These eggs contain spores which will germinate and form new fungal bodies. Bird's Nests are not particularly rare or exotic. I happened to notice these one morning growing in the old, wet ashes around my campfire as I prepared breakfast!
