Members of the genus Chrysovirus infect ascomycetous or basidiomycetous fungi. All members have four dsRNA genome segments ranging from 2.5 to 3.6 kbp. The genome comprises 11.5-12.8 kbp in total. The dsRNA segments are individually encapsidated in separate particles.
See discussion under family description.
Species demarcation criteria:
Species demarcation considers a combination of each of the criteria listed above. While nucleotide and amino acid sequence relatedness are important criteria for species demarcation, the other listed criteria may be useful in demarcation of genetically closely related viruses that nevertheless belong to different species.
