Members of the family Fimoviridae, order Bunyavirales are plant viruses with segmented, linear, single-stranded, negative-sense RNA genomes. They are distantly related to orthotospoviruses and orthobunyaviruses of the families Tospoviridae and Peribunyaviridae, respectively. The family Fimoviridae includes the genus Emaravirus, which comprises several species with European mountain ash ringspot-associated emaravirus as the type species. Fimoviruses are transmitted to plants by eriophyid mite vectors and induce similar characteristic cytopathologies in their host plants, including the presence of double membrane-bound bodies in the cytoplasm of the virus-infected cells. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the taxonomy of the Fimoviridae, which is available at www.ictv.global/report/fimoviridae.

Article Synopsis
- Before 2017, a family of viruses related to the Bunyamwera virus included five genera of arthropod and rodent viruses with tri-segmented negative-sense RNA genomes.
- In 2017, the International Committee on Taxonomy of Viruses promoted this family to an order and added more families for various non-segmented to polysegmented viruses across different life forms.
- By April 2024, due to ongoing discoveries, this order was elevated to a class, now encompassing hundreds of viruses, many of which are pathogenic to humans, animals, plants, and fungi.

Aspen mosaic-associated virus (AsMaV) is a newly identified , in the family , , associated with mosaic symptoms in aspen trees (). Aspen trees are widely distributed in Europe and understanding the population structure of AsMaV may aid in the development of better management strategies. The virus genome consists of five negative-sense single-stranded RNA (-ssRNA) molecules.

Article Synopsis
- In April 2023, the International Committee on Taxonomy of Viruses (ICTV) approved changes to the phylum's classification during their annual vote.
- The update included the addition of one new family, 14 new genera, and 140 new species.
- Additionally, the taxonomy featured the renaming of two genera and 538 species, along with the removal of one species and the abolition of four others.
