High Quality Content by WIKIPEDIA articles! Lycoperdon echinatum, commonly known as the spiny puffball or the spring puffball, is a type of puffball mushroom in the genus Lycoperdon. 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 Lycoperdon echinatum is closely related to the puffball genus Handkea.
