Meaning and Definition
The inner layer of the double-walled peridium (enclosing membrane) of some fungi, particularly puffballs.
In mycology, the specific structural term for the inner wall of a spore-bearing fruiting body, which often dehisces or opens in a characteristic way (e.g., via an apical pore) to release spores. It contrasts with the outer layer, the exoperidium.

FAQ
Frequently Asked Questions
Its primary function is to contain and protect the spore mass (gleba) until maturity, after which it often opens in a specific way to allow for spore release.
No, it is a specific mycological (fungal) term. Plants have different structural terms like endodermis or endocarp.
Typically, no. The term 'endoperidium' inherently implies a double-walled structure; a single wall is just called a peridium. However, the exoperidium may weather away, leaving only the endoperidium visible.
Only if you are a mycologist, botanist, biologist, or have a deep interest in fungal biology. It is not part of general vocabulary.
