ICTV Virus Taxonomy Profile: 2023.

is a family of capsidless viruses with positive-sense RNA genomes of 7.3-18.3 kb that possess either a single large open reading frame (ORF) or two ORFs. The ORFs appear to be translated from genomic RNA by non-canonical mechanisms, i.e. internal ribosome entry site- and stop/restart translation. This family includes the genera , , , , , , and . Hypovirids have been detected in ascomycetous and basidiomycetous filamentous fungi and are considered to replicate in host, Golgi apparatus-derived, lipid vesicles that contain virus dsRNA as the replicative form. Some hypovirids induce hypovirulence to host fungi, while others do not. This is a summary of the ICTV report on the family , which is available at www.ictv.global/report/hypoviridae.
