The genus is distinguished on the basis of genetic characters.
No surface morphology is visible by EM.
Avihepatoviruses are both heat and acid stable.
The genus is distinguished on the basis of genetic characters.
No details are available on the morphology of virions.
No details are available on physicochemical and physical properties.
The genus is distinguished on the basis of genetic characters. The known ampiviruses have rather large protease and polymerase proteins compared to those of other picornaviruses.

Tobraviruses have a bipartite genome, a “30K”-like cell-to-cell movement protein and are transmitted by trichodorid nematodes.
Pomoviruses have three genomic RNAs, a “triple gene block” set of cell-to-cell movement proteins and are transmitted by root-infecting vectors in the family Plasmodiophorales, once described as fungi but now classified as Cercozoa.
Pecluviruses have a bipartite genome, a “triple gene block” set of cell-to-cell movement proteins and are transmitted by root-infecting vectors in the family Plasmodiphorales, once described as fungi but now classified as Cercozoa.
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).
