Lycoperdon perlatum, commonly known as the common earthball or the gem-studded puffball, is a type of fungus found in forests and grasslands. It has a round, white to tan appearance, often covered with small, spiky projections. This mushroom typically grows in clusters and can reach up to 10 cm in diameter. The fruiting body of Lycoperdon perlatum releases spores when mature, which are dispersed by wind or rain. While it is not considered edible, it plays an important role in the ecosystem by decomposing organic matter and enriching the soil.
