Anamorph and Teleomorph Names for Candida Species

What to know

Candida species may have two names that correlate to the growth state of the fungus: an anamorph name associated with asexual growth and replication (mitosis only) of the fungus and a teleomorph name associated with the sexual growth and replication.

Beware of alternate names for Candida species

Candida species may have two names that correlate to the growth state of the fungus: an anamorph name associated with asexual growth and replication (mitosis only) of the fungus and a teleomorph name associated with the sexual growth and replication. Examples of dual names are listed below. Certain identification methods (e.g., MALDI-TOF or DNA sequencing) may identify the organism only by its teleomorph name, which may not include the word Candida even though this organism is indeed a species of Candida.

The table below is intended to help laboratory workers understand which Candida yeasts have multiple names.

More information

In the new guidance document, M64, the Clinical and Laboratory Standards Institute will recommend using the anamorph name for common fungi, such as Candida and Aspergillus, in laboratory reports as the preferred terminology by clinicians. A note can be added to the report such as "This isolate is also identified by the teleomorph name xxx".
