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. Molecular analysis indicates that Lycoperdon echinatum is closely related to the puffball genus Handkea. Initially white in color, the puffballs turn a dark brown as they mature, at the same time changing from nearly round to somewhat flattened. The fruit bodies are edible when young, when the interior is white and firm and before it has turned into a powdery brown mass of spores. Young specimens of L. echinatum resemble another edible spiny puffball, Lycoperdon pulcherrimum, but this latter species does not turn brown as it ages. Laboratory tests have shown that extracts of the fruit bodies can inhibit the growth of several bacteria that are pathogenic to humans. (more...)
