deuteromycota
Definition
- Noun:
- A large and heterogeneous form division of fungi: Deuteromycota refers to a major taxonomic grouping of fungi that is characterized by its diversity and lack of a known sexually reproductive stage in its life cycle. Members are often classified based on their asexual reproductive structures.
Usage Examples
- Noun:
- The Deuteromycota division includes many fungi of economic importance, such as those that cause plant diseases.
- Because no sexual phase is known, fungi in the Deuteromycota are sometimes called "fungi imperfecti."
- Penicillium is a well-known genus historically placed within the Deuteromycota.
Advanced Usage
- "Deuteromycota" as a taxonomic category: While once a formal taxonomic division, this term is now considered an informal, polyphyletic grouping. Modern fungal taxonomy, based on DNA analysis, often reclassifies these fungi into other phyla like Ascomycota.
- Many species formerly classified under Deuteromycota have been reassigned to the Ascomycota based on molecular evidence.
Variants and Related Words
- Deuteromycetes (n): Another name for the class of fungi within the Deuteromycota.
- Deuteromycetes is a class of fungi with no known sexual reproductive stage.
- Fungi Imperfecti (n): A common synonym for Deuteromycota, meaning "imperfect fungi."

Synonyms
- Fungi Imperfecti: Imperfect fungi.
- Anamorphic fungi: A term referring to the asexual (anamorph) state of these fungi.
Related Phrases / Terms
- Asexual reproduction: The primary mode of reproduction known for this group, typically via conidia (spores).
- Fungi in the Deuteromycota reproduce solely by asexual means.
- Form division: A taxonomic category based on morphology rather than phylogenetic relationship, which applies to this group.
- Deuteromycota was established as a form division due to the lack of sexual reproductive structures.
Noun
