Hordeiviruses have three genomic RNAs and encode a “triple gene block” set of cell-to-cell movement proteins. They differ from viruses of all other genera because the RdRP is encoded on a separate RNA (rather than by readthrough of a stop codon from an upstream replication protein encoding ORF).
Furoviruses have a bipartite genome, a “30K”-like cell-to-cell movement protein and are transmitted by root-infecting vectors in the family Plasmodiphorales, once described as fungi but now classified as Cercozoa.

Since only one genus is currently recognized, the genus description corresponds to the family description.
Benyviruses are distinguished by coat protein sequences of less than 90% amino acid identity, distant serological relations and distinct host ranges.
