peridium

The peridium of the puffball protects the developing spores from the environment.

Look closely at how the peridium ruptures to allow the spores to escape.

The specimen has a thick, leathery peridium that resists decay.

I wonder if this species has a double layered peridium.

The peridium eventually breaks open at the top to form a small pore.

We need to examine the structure of the peridium under the microscope.

A thin peridium makes the fungus more susceptible to premature rupture.

The outer peridium is often textured or warty in certain species.

Once the peridium splits, a cloud of spores is released into the wind.
