The Pear Puffball (Apioperdon pyriforme) is a common and easily recognizable puffball mushroom. It is typically found growing on decaying wood, often in clusters. While generally considered edible when young and firm, it's crucial to correctly identify it to avoid confusion with poisonous look-alikes.
How to Identify
- Cap
- Technically, puffballs do not have a cap and stem like typical mushrooms. The fruiting body is pear-shaped to roundish, 1-5 cm across, and attached to a small, sterile base.
- Gills
- Absent. Puffballs do not have gills.
- Stem
- A sterile base that attaches the fruiting body to the substrate. It is not a true stem.
- Flesh
- The internal flesh (gleba) is white and firm when young, turning yellowish and eventually brownish-olive as it matures. Only eat when the flesh is uniformly white.
- Fruiting body
- Pear-shaped to roundish, attached to a sterile base. White when young, turning brownish with age.
- Habitat
- Grows on decaying wood, often in dense clusters.
Key Facts
- Cap surfaces: Smooth, becoming cracked with age
- Growth Form: Clustered
- Spore Print: Olive-brown
- Body color: White to brownish
- Odor: Mild, mushroomy when young
- Flesh bruises: Does not bruise
- Height: 2-7 cm
- Cap Diameter: 1-5 cm

Safe
SafeMature puffballs with yellowish or brownish interiors can cause gastrointestinal upset. Earthballs (Scleroderma spp.) are toxic look-alikes that have a firm, dark interior even when young. Always slice puffballs open to ensure they are pure white inside before consumption.
