Meaning and Definition
A closed, spherical fruiting body in certain fungi and bryophytes (like mosses) that does not open regularly to release spores; it is non-dehiscent.
In botany and mycology, a specific type of durable, non-opening spore capsule, often associated with species that rely on the decay of the surrounding tissue or external forces (like animal ingestion or crushing) for spore dispersal. It represents an evolutionary adaptation for survival in specific environments.

FAQ
Frequently Asked Questions
Not exactly. 'Cleistocarp' is a broader botanical term for a closed fruiting body in plants like mosses and some fungi. 'Cleistothecium' is a specific type of closed ascocarp (spore-bearing structure) in certain fungi (like Aspergillus). They are often used synonymously in older fungal literature, but modern usage tends to distinguish them.
Spores are not actively released. They escape only when the cleistocarp wall decays, ruptures due to environmental pressure (e.g., freezing, animal activity), or is digested by an animal that then disperses the spores.
Primarily in certain groups of bryophytes (mosses), fungi (e.g., powdery mildews), and some algae. It is a morphological term, not limited to a single taxonomic group.
It is a highly specialized term in the jargon of botany and mycology. It describes a specific, non-common reproductive structure, so it is not needed outside these scientific fields, making its overall frequency in language extremely low.
