Meaning and Definition
A fungus belonging to an obsolete taxonomic group (Deuteromycota or Fungi Imperfecti) characterized by reproducing asexually through conidia, lacking a known sexual reproductive stage.
In modern mycology, the term is used historically or informally for fungi whose sexual phase (teleomorph) is unidentified, but which are known to reproduce asexually (anamorph). Many are now reclassified into Ascomycota or Basidiomycota when their sexual stage is discovered.
Dialectal Variation
British vs American Usage
Differences
No significant variation in meaning. US texts may use 'mitosporic fungi' or 'anamorphic fungi' more frequently as modern alternatives.
Connotations
In both regions, the term carries a connotation of provisional or incomplete classification. It may imply the fungus is not fully understood taxonomically.
Frequency
Extremely low frequency in general English. Used almost exclusively in academic mycology, phytopathology, and microbiology. Slightly more common in British historical taxonomic texts.

Common Mistakes When Using “deuteromycete”
- Mispronouncing 'deutero-' as 'detro-'.

FAQ
Frequently Asked Questions
No. Modern fungal taxonomy, based on molecular phylogenetics, has abandoned Deuteromycota as a formal taxon. Fungi once placed there are now distributed within the Ascomycota and Basidiomycota based on DNA evidence.
It persists in diagnostic contexts (e.g., plant disease manuals), historical literature, and as a practical term for an asexual morph (anamorph) when the sexual connection is unconfirmed.
Anamorph refers to the asexual reproductive stage (formerly 'deuteromycete'). Teleomorph refers to the sexual reproductive stage. Holomorph encompasses the whole fungus, including all its reproductive forms.
Historically, yes—when only its anamorph was known, it was a 'deuteromycete.' Once its teleomorph (sexual stage) is discovered, it receives a name based on that stage and is reclassified into Ascomycota or Basidiomycota. The anamorph name may still be used for the asexual form.

Deuteromycete is usually technical/scientific in register.
Deuteromycete: in British English it is pronounced /ˌdjuːtərə(ʊ)ˈmʌɪsiːt/, and in American English it is pronounced /ˌduːtəroʊˈmaɪsiːt/. Tap the audio buttons above to hear it.

Learning
Memory Aids
Mnemonic
DEUTERO (second) + MYCETE (fungus) = a 'second-class' or incomplete fungus because its full life cycle (sexual stage) wasn't known.
Conceptual Metaphor
A 'placeholder name' or a 'file for unsolved cases' in the fungal world.
