The giant puffball (Calvatia gigantea, syn. Langermannia gigantea, Lycoperdon gigantea) is an easily identifiable meadow mushroom with extraordinarily large fruiting bodies from the mushroom family. It used to belong to the class or subclass of the abdominal fungi (Gastromycetes or Gastromycetidae), which, according to recent scientific findings, no longer have any taxonomic significance.
-Calvatia gigantea is the largest species of the puffball family and is also the most common species.
-Giant puffballs appear to rapidly pass into the inedible spore-producing stage after being exposed to a day or so of sunshine.
-The very largest specimens of the giant puffball ever reported were more than 150 cm in diameter, 45 cm high and would have weighed more than 100 kg when fresh.
-They grow and increase in size over a period of nearly two weeks before they reach maturity.
