Members of the genus Sclerotimonavirus are distinct from those of other genera by phylogenetic analysis of the RdRP gene (Figure 5.Mymonaviridae) with <32% amino acid sequence identity for the L protein. The genome is a single molecule of linear, negative-sense RNA of about 10 kb with five or six ORFs separated by non-coding intergenic regions containing highly conserved gene-junction sequences. See family section for a description of virions, antigenicity, and biology. Members have been identified from fungi, or detected by high-throughput sequencing in fungi, lesions of plant caused fungi, mycelial mass of oomycetes, and soil.
Species demarcation criteria
Members of different species in the genus differ by >30% in nucleoprotein amino acid sequence and by >30% in their coding-complete or complete genome nucleotide sequence.
