Curtis's Puffball

Curtis's puffball is a small, gregarious fungus notable for forming distinctive arcs or fairy rings across sunlit lawns and pastures. The spherical fruit bodies are initially coated in soft, clustering spines that slough off as they age, revealing a smooth papery skin beneath. When mature, an apical pore opens at the summit, allowing raindrops and passing animals to compress the casing and puff powdery clouds of olive-brown spores into the breeze.
