Deuteromycetes

Part of speech: noun

Definitions

1. A group of fungi characterized by their lack of a known sexual reproduction stage, primarily existing in asexual forms
2. Often considered imperfect fungi, these organisms include species commonly found in various environments
3. This classification highlights fungi that reproduce via conidia or other asexual methods without documented sexual cycles

Etymology: Deuteromycetes is the plural of "deuteromycete", the name for a group of fungi that were long classified by the form they took when reproducing asexually. The name is built from Greek: "deuteros" meaning "second", and "mykes" meaning "fungus", the second element also seen in words such as mycology. The label thus describes a fungus placed in a second category, one defined by what its reproduction looked like rather than by any sexual cycle that had been observed. That grouping was never a true family tree. Fungi that were known only from their asexual stages were gathered here for convenience, and as researchers later linked many of them to sexual forms in the Ascomycota and Basidiomycota, the members were moved into those phyla. For this reason the name is now mainly of historical interest, though it remains common in older mycology texts and in discussions of fungal classification.

Synonyms: fungi imperfecti
