Victorivirus is a genus of viruses, in the family Totiviridae . Filamentous fungi serve as natural hosts. There are 14 species in this genus. [1] [2]
Viruses in Victorivirus are non-enveloped, with icosahedral geometries, and T=2 symmetry. The diameter is around 40 nm. Genomes are linear, around 4.6-6.7kb in length. The genome has 2 open reading frames. [1]

Viral replication is cytoplasmic. Entry into the host cell is achieved by virus remains intracellular. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. Translation takes place by RNA termination-reinitiation. The virus exits the host cell by cell to cell movement. Filamentous fungi serve as the natural host. [1]

The genus Victorivirus includes the following species: [2]
Totiviridae is a family of double-stranded RNA viruses. Giardia lamblia, leishmania, trichomonas vaginalis, and fungi serve as natural hosts. The name of the group derives from Latin toti which means undivided or whole. There are 28 species in this family, assigned to 5 genera.
Closteroviridae is a family of viruses. Plants serve as natural hosts. There are four genera and 59 species in this family, seven of which are unassigned to a genus. Diseases associated with this family include: yellowing and necrosis, particularly affecting the phloem.
Totivirus is a genus of double-stranded RNA viruses in the family Totiviridae. Fungi serve as natural hosts. The name of the group derives from Latin toti which means undivided or whole. There are seven species in this genus.
Alphachrysovirus is a genus of double-stranded RNA viruses. It is one of two genera in the family Chrysoviridae. They infect fungi, in particular Penicillium. Their name is derived from the Greek word chrysos which means yellow-green. There are 20 species in this genus.
Trichovirus is a genus of viruses in the order Tymovirales, in the family Betaflexiviridae. Plants, specifically angiosperms such as pome fruits, citrus, and pear, serve as natural hosts for this plant pathogen. There are seven species in this genus.
Alphaflexiviridae is a family of viruses in the order Tymovirales. Plants and fungi serve as natural hosts. There are 65 species in this family, assigned to six genera. Diseases associated with this family include: mosaic and ringspot symptoms.
Betaflexiviridae is a family of viruses in the order Tymovirales. Plants and fungi serve as natural hosts. There are 108 species in this family, assigned to 13 genera in two subfamilies. Diseases associated with this family include mosaic and ringspot symptoms.
Gammaflexiviridae is a family of viruses in the order Tymovirales. Fungi serve as natural hosts. There is only one genus in the family, Mycoflexivirus, which has one species: Botrytis virus F.
Macluravirus is a genus of viruses, in the family Potyviridae. Plants serve as natural hosts. There are ten species in this genus.
Allexivirus is a genus of viruses in the order Tymovirales, in the family Alphaflexiviridae. Shallot, onion, and garlic serve as natural hosts. There are 13 species in this genus, seven of which are assigned to a subgenus. Diseases associated with this genus include: mosaic and ringspot symptoms.
Botrexvirus is a genus of viruses in the order Tymovirales, in the family Alphaflexiviridae. Fungi serve as natural hosts. There is only one species in this genus: Botrytis virus X.
Brambyvirus is a genus of viruses, in the family Potyviridae. Plants serve as natural hosts. There is only one species in this genus: Blackberry virus Y.
Capillovirus is a genus of viruses in the order Tymovirales, in the family Betaflexiviridae. Plants, pome fruits, citrus, and pear serve as natural hosts. There are four species in this genus. Diseases associated with this genus include: abnormal graft union, possibly black necrotic leaf spot disease.
Mitovirus is a genus of positive-strand RNA viruses, in the family Mitoviridae. Fungi serve as natural hosts. There are five species in the genus.
Mycoreovirus is a genus of double-stranded RNA viruses in the family Reoviridae and subfamily Spinareovirinae. Fungi serve as natural hosts. Diseases associated with this genus include: hypovirulence of the fungal host. The name of the group derives from Ancient Greek myco which means fungus. There are three species in this genus.
Megabirnaviridae is a family of double-stranded RNA viruses with one genus Megabirnavirus which infects fungi. The group name derives from member's bipartite dsRNA genome and mega that is greater genome size than families Birnaviridae and Picobirnaviridae. There is only one species in this family: Rosellinia necatrix megabirnavirus 1. Diseases associated with this family include: reduced host virulence.
Quadriviridae is a family of double-stranded RNA viruses with a single genus Quadrivirus. The fungi Rosellinia necatrix serves as a natural host. The name of the group derives from the quadripartite genome of its members where in Latin quad means four. There is only one species in this family: Rosellinia necatrix quadrivirus 1.
Citrivirus is a genus of viruses in the order Tymovirales, in the family Betaflexiviridae. Plants serve as natural hosts. There is only one species in this genus: Citrus leaf blotch virus.
Tepovirus is a genus of viruses in the order Tymovirales, in the family Betaflexiviridae. Plants as well as some other root and tuber crops in the andes serve as natural hosts. There are two species in this genus.
Velarivirus is a genus of viruses, in the family Closteroviridae. Plants serve as natural hosts. There are eight species in this genus. Diseases associated with this genus include: GLRaV-7: symptomless in white-berried grapevine cultivar from Albania. However, it induces leafroll symptoms onto grafted cv. cabernet.
