Lycoperdon echinatum

Lycoperdon echinatum, commonly known as the spiny puffball or the spring puffball, is a type of puffball mushroom in the family Agaricaceae. The saprobic species has been found in Africa, Europe, Central America, and North America, where it grows on soil in deciduous woods, glades, and pastures. It has been proposed that North American specimens be considered a separate species, Lycoperdon americanum, but this suggestion has not been followed by most authors. Molecular analysis indicates that L. echinatum is closely related to the puffball genus Handkea. The fruit bodies of L. echinatum are 2–4 cm (0.8–1.6 in) wide by 2–3.5 cm (0.8–1.4 in) tall, supported by a small base, and densely covered with spines that are up to 0.6 cm (0.2 in) long. The spines can fall off in maturity, leaving a net-like pattern of scars on the underlying surface. Initially white in color, the puffballs turn a dark brown as they mature, at the same time changing from nearly round to somewhat flattened. Young spe......read more on Wikipedia.
