According to the Missouri Department of Conservation, Calvatia gigantea typically grows up to 20–50 centimetres (8– 19 + 1 ⁄ 2 in) wide and high. [2] According to First Nature, it "can grow to 80 cm diameter and weigh several kilograms". [3] A specimen weighing over 23 kg (51 lb) was recorded in Thunder Bay, Ontario, Canada. [4]
The giant puffball, Calvatia gigantea (earlier classified as Lycoperdon giganteum), reaches 1 foot (0.30 m) or more in diameter, and is difficult to mistake for any other fungus. It has been estimated that, when mature, a large specimen of this fungus will produce around 7 × 10 12 spores, which is more than any other known organism.
Seven U.S. states, California, Minnesota, Oregon, Texas, Utah, Vermont and Illinois have officially declared a state mushroom.Minnesota was the first to declare a species; Morchella esculenta was chosen as its state mushroom in 1984, and codified into Statute in 2010. [1]
This puffball has been variously placed in the genera Bovista, Handkea, Calvatia, and Utraria.In 1989, German mycologist Hanns Kreisel described the genus Handkea to include species of Calvatia that had distinct microscopic features: Handkea species had a unique type of capillitium (coarse thick-walled hyphae in the gleba), with curvy slits instead of the usual pores. [1]
Handkea utriformis, synonymous with Lycoperdon utriforme, Lycoperdon caelatum or Calvatia utriformis, is a species of the puffball family Lycoperdaceae.A rather large mushroom, it may reach dimensions of up to 25 cm (10 in) broad by 20 cm (8 in) tall.
Calvatia is a genus of puffball mushrooms that includes the giant puffball C. gigantea.It was formerly classified within the now-obsolete order Lycoperdales, which, following a restructuring of fungal taxonomy brought about by molecular phylogeny, has been split; the puffballs, Calvatia spp. are now placed in the family Lycoperdaceae of the order Agaricales.
Calvatia craniiformis is edible when the gleba is firm and white, unlike the pictured specimen. Calvatia craniiformis is an edible species. [18] Young puffballs with a firm, white gleba have a mild odor and pleasant taste. [12] Early 20th-century mycologist Charles McIlvaine noted over a century ago that "the slightest change to yellow makes it ...
Calvatia booniana, commonly known as the western giant puffball, [1] is a puffball mushroom that can grow 10 to 70 centimetres (3.9 to 28 in) in diameter, as large as its close relative, the giant puffball of eastern North America and Europe. [2]
