multisporus

Multisporus is a term used in mycology to describe certain fungi that produce more than four spores per ascospore. In the context of ascomycetes, the sexual spores (ascospores) are typically contained within an ascus. The number of ascospores within an ascus is usually a characteristic feature used for fungal identification and classification. While many ascomycetes regularly produce eight ascospores per ascus, some species, or even variations within a species, can produce a higher number. The term "multisporus" specifically refers to this characteristic of having multiple spores, generally implying more than the standard eight, although the exact threshold can vary in usage. This trait can be genetically determined or influenced by environmental factors during ascospore development. Studying the spore count in fungal species is a fundamental aspect of their taxonomy and evolutionary biology. It provides insights into the reproductive strategies and genetic diversity of these organisms.
