Lycoperdon perlatum (Common Puffball): A species of puffball fungus belong to family Agaricaceae. Fruit bodies are 2.5-6.5 cm wide and 2.5-8 cm tall. It is edible. This puffball species is round to pear or turban-shaped usually with an elongate, stalk-like base. When young it is white and covered with conical white spines with shorter spines and granules between them. With maturity the longer conical spines are usually broken off leaving a pattern of pits or net-like scars on an aging yellow-brown surface. The spore-producing internal tissue (gleba) is moist and white at first, turning olive-brown and powdery when mature. A pore-like mouth forms (the ostiole) at the apex at maturity allowing spores to be "puffed out" when the outer case is disturbed by raindrops or twigs striking it.
