Definition
Noun: 1. A taxonomic genus of fungi: A form genus of imperfect fungi (Deuteromycota) characterized by the production of hyaline (colorless or transparent) spores and conidiophores (the specialized fungal structures that bear the spores).
Usage Notes
- This is a highly specialized scientific term used in mycology (the study of fungi) and plant pathology.
- It is a taxonomic name and should be italicized in formal scientific writing: .
- The term "form genus" indicates it is a classification based primarily on morphological characteristics (like spore shape and color) rather than genetic or reproductive features, which is common for imperfect fungi whose sexual reproductive stages are unknown.
Examples
- Scientific Context:
- The pathogen causing white leaf spot on crucifers was classified under the genus Cercosporella.
- Several species within genus Cercosporella are known to be plant pathogens.
Advanced Usage
- The genus name is often used in its abbreviated form after first mention in a scientific text: "The infection was caused by spp." (where "spp." stands for multiple species).
Variants and Related Words
- Cercosporella (n): The standard, non-italicized form used in general discussion.
- cercosporella (n, adj): When used as a common name or modifier (e.g., a cercosporella infection).
Synonyms

- Hyphomycete genus: A broader synonym referring to its classification as a genus of fungi that produce spores on conidiophores.
