This small, smooth peridium western puffball, common in pastures or (in this case) a soccer field, is not hard to find nor to identify. In maturity the spore mass (gleba) becomes at first slightly yellowish-green, and matures to a powdery mass of dull brown spores held together by threads. During a good wind, these often tumble about, spreading their spores everywhere – a unique dispersal system. This particular specimen had, alas, already been punted before being found.
