Watering

Keep the wood substrate consistently moist but not waterlogged.

Feeding

Do not fertilize this fungus as it derives nutrients from wood decay.

Pruning

Pruning is not applicable for this fungal species.

Repotting

Repotting is not applicable as this species requires specific wood logs.

Safety

People

It is considered edible when the interior is pure white, but it must be cooked thoroughly.

Children

Keep children away from mature specimens to prevent them from inhaling the cloud of spores.

Contact allergens

Mature specimens release large clouds of spores that can irritate the eyes or skin.

Airborne allergens

Inhaling large amounts of the mature spores can cause respiratory irritation.

Edibility

Only consume if you are an expert mycologist, as misidentification with toxic species can be fatal.

Questions people ask

Is it safe to eat?

Only if the interior is firm and white, but always confirm with an expert.

Where does it grow?

You will find it growing on rotting logs and stumps in forests.

Where the name comes from

The name Apioperdon comes from the Greek words for pear and puffball, reflecting its distinct shape.

Good to know

• The name pyriforme refers to its pear shape.
• It is one of the few puffballs that grows in clusters on wood.
• The spores are dispersed by raindrops hitting the top of the fruit body.
