|ascospore (ās'kə-spôr') Pronunciation Key
A sexually produced fungal spore formed within an ascus of ascomycetes. Ascospores have a haploid number of chromosomes and are formed by meiosis of the diploid zygote that results when the nuclei of sexually compatible hyphae fuse together. When an ascospore is released and lands in a place that is rich in nutrients, it germinates and sends out hyphae of its own.
