Bird's Nest Fungus Egg (Peridiole)

Natural Habitat

Damp environments, typically found on mulch, rotting wood, or manure in gardens and forests.

Diet & Feeding

Decomposing organic matter (saprotrophic).

Behavior Patterns

These are not insects, but the spore-containing structures of a fungus. They are splash-dispersed; when a raindrop hits the cup-shaped fruiting body, these eggs are ejected several feet away where they stick to surfaces to grow.

Risks & Benefits

Harmless to humans and pets. They are beneficial decomposers that help break down organic material and return nutrients to the soil.
