Narnavirus is a genus of positive-strand RNA viruses in the family Narnaviridae.

This fungal–bacterial-viral system represents an outstanding model to investigate three-way microbial symbioses and their evolution.").

[3] Narnaviruses have a naked RNA genome without a virion and derive their name from this feature.

The genome has one open reading frame which encodes the RNA-dependent RNA polymerase (RdRp).

The genome is associated with the RdRp in the cytoplasm of the fungi host and forms a naked ribonucleoprotein complex.
