Characteristics of Calvatia gigantea

Calvatia gigantea is characterized by its enormous size, reaching diameters of up to 75 cm and weighing up to 25 kg. Its shape is usually globular or subglobular, with a smooth, white surface in its early stages. As it matures, the surface becomes a mottled greenish-brown color and breaks into irregular plates.

Macroscopic description:

  • Carpophore: The carpophore, or body of the mushroom, is sessile, meaning it has no stem. It is directly attached to the substrate by rhizomorphs, filamentous structures that serve as anchors.
  • Exoperidium: The outer layer, called the exoperidium, is white at first and turns a mottled greenish brown with age. It breaks into irregular plates when mature.
  • Endoperidium: Under the exoperidium is the endoperidium, a very thin, brittle layer that also breaks into plates.
  • Gleba: The interior of the carpophore, known as the gleba, is white and compact when young. With maturity, it turns brown to yellowish-green and powdery, releasing the spores.
  • Base: Once the spores have been released, the base of the carpophore becomes a woody, root-like remnant.

Habitat of Calvatia gigantea

Calvatia gigantea grows in meadows and pastures, usually on grass. It is a solitary species, although it can also be found in small groups. It prefers soils rich in organic matter and with good moisture content.
