Chrysovirus is a genus of viruses. It is the only genus in the family Chrysoviridae.[1] They are class III double stranded RNA viruses which infect fungi, in particular Penicillium. Their name is derived from the Greek word chrysos which means yellow-green. There are currently nine species in this genus including the type species Penicillium chrysogenum virus.[2][3]

Structure
Viruses in the genus Chrysovirus are non-enveloped, with icosahedral geometries, and T=1, T=2 symmetry. The diameter is around 35-40 nm. Genomes are linear and segmented, around 12.5kbp in length. The genome codes for 4 proteins. The genome has three double stranded RNA segments. All have extended highly conserved terminal sequences at both ends.[2][3]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |

| Chrysovirus | Icosahedral | T=1 | Non-enveloped | Linear | Segmented |
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. The virus exits the host cell by cell to cell movement. Fungi serve as the natural host.[2][3]
