Genomoviridae is a family of single stranded DNA viruses that mainly infect fungi.

In Rep-based phylogenies, genomoviruses form a sister clade to plant viruses of the family Geminiviridae.

[2] The genus name Gemycircularvirus stands for Gemini-like myco-infecting circular virus.

[1][3][8] The genera in this family are:[4] These viruses have circular single-stranded genomes of 2.1–2.2 kilobases in length.

[1] The monopartite genomes encode two proteins—a Rep (replicator) and a CP (capsid) protein.
