Genus: Betascleroulivirus
Family: Botourmiaviridae
Genus: Betascleroulivirus
Distinguishing features
Betasclerouliviruses have a mono-segmented genome and infect fungi. Some members of the genus have been identified in association with grapevine leaves infected with the oomycete Plasmopara viticola. Betasclerouliviruses are phylogenetically distinct from other botourmiaviruses.
Virion
No true virions are associated with betasclerouliviruses since their genomes have no capsid protein gene.
