teleutospore
RareTechnical/Scientific
Definition
Meaning
A thick-walled resting spore of rust fungi that survives winter.
A specific type of overwintering spore in the complex life cycle of rust fungi (Pucciniales), which germinates in spring to produce basidia and basidiospores, thereby initiating a new infection cycle.
Linguistics
Semantic Notes
This term is specific to mycology, particularly phytopathology. It is synonymous with teliospore in modern terminology, though 'teleutospore' is the older, more specific term within the rust fungi life cycle stages (e.g., urediniospore, aeciospore, teleutospore).
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. The term is identical in spelling and meaning. The older term 'teleutospore' might be slightly more common in historical British texts, while 'teliospore' is the preferred modern term globally.
Connotations
Purely technical and scientific; no regional connotations.
Frequency
Extremely low frequency in all registers and regions. Used almost exclusively in specialized mycology and plant pathology literature.

Examples
By Part of Speech
adjective
British English
- The teleutospore stage is critical.
- Teleutospore germination requires specific conditions.
American English
- Teleutospore development was observed.
- The teleutospore wall is highly resistant.
Examples
By CEFR Level
- The black spots on the leaf contain the fungus's teleutospores.
- Under the microscope, the thick, ornamented walls of the teleutospores were clearly visible, confirming the species as *Puccinia graminis*.
- The teleutospores overwinter on plant debris, completing the pathogen's life cycle.
Learning
Memory Aids
Mnemonic
Imagine a telephone (teleu-to) telling a spore it's time to sleep (rest) for the winter. 'Teleutospore' = the 'final' (from Greek 'teleutē') spore stage before dormancy.
Conceptual Metaphor
A SEED VAULT or SURVIVAL POD; a durable, protected structure designed to ensure the organism's survival through harsh conditions and enable future propagation.

Common Pitfalls
Translation Traps (for Russian speakers)
- Не путать с более общим термином 'спора' (spore).
- Может переводиться как 'телиоспора' (teliospore) или устаревшее 'телитоспора'. Контекст важен.
Common Mistakes
- Misspelling: 'teletospore', 'teleutspore'.
- Confusing it with other spore types like basidiospores or conidia.
- Using it in non-fungal contexts.

FAQ
Frequently Asked Questions
Essentially, yes. 'Teliospore' is the modern, more general term for the thick-walled resting spore in rusts and smuts. 'Teleutospore' is the older, specific term for the teliospore stage in rust fungi (Pucciniales).
Only in very specialized academic or professional contexts related to plant pathology, mycology, or agricultural science. It is not a word for general use.
The most common pronunciation is /təˈluːtəˌspɔːr/ (tuh-LOO-tuh-spor), with the primary stress on the second syllable.
No, not directly. After overwintering, a teleutospore germinates to produce a basidium, which in turn produces basidiospores. It is these basidiospores that infect the primary host plant.
