Puffball Mushroom
Calvatia giganteaAlso known as Giant Puffball
Giant puffballs produce some of the largest fruiting bodies in the fungal kingdom, often appearing overnight in grassy fields, pastures, and open woodlands. As the internal spore mass matures, it transforms from firm white flesh into billions of olive-brown spores released when the outer skin ruptures. These saprobic fungi play an essential role breaking down organic matter in temperate soils across the Northern Hemisphere.

- Very high
- Why interaction risk is low
- Many edible mushrooms have toxic look-alikes; never eat wild fungi based on app identification alone.
Responsible observation
- Identification: Look for smooth, white, round fruiting bodies resting directly on grass in late summer or autumn.
- Spore Release: Avoid inhaling dense clouds of dry spores released when mature puffballs are stepped on or disturbed.
- Safety Precaution: Never ingest wild fungi based on digital identification, as dangerous species can share similar early growth stages.
