Meaning and Definition
A taxonomic category used in paleontology and mycology for classifying fossil or fungal specimens based on their morphological characteristics when their true biological relationships are uncertain.
In a broader sense, a provisional classification grouping based on form or structure rather than confirmed evolutionary lineage.
Dialectal Variation

FAQ
Frequently Asked Questions
No, it is an artificial classification category used for convenience when biological relationships cannot be determined. It is a pragmatic tool, not a reflection of true evolutionary lineage.
Primarily in paleontology (for fossil plants, spores, pollen) and mycology (for fungi known only from asexual stages or incomplete specimens).
Yes, that is a common occurrence. Organisms from different evolutionary lines that convergently evolved similar forms can end up in the same form genus.
A 'form genus' is based on morphology alone and is provisional. A 'type genus' is the representative genus that defines a family or higher taxon and is based on established biological classification.
