'''Hypoviridae''' is a fungal virus (infects [[fungi]]) which is rather poorly characterized by a structure. No true viral particles are associated with this virus and [[vesicles]] are devoid of any detectable viral structural proteins. However viral nucleic acid can still be isolated from infected tissue. Also [[pleomorphic]] vesicles surrounded by [[rough endoplasmic reticulum]] occur in infected tissue. Once again, they do not contain typical viral structures <ref>Patrik J. Hoegger, Ursula Heiniger, Ottmar Holdenrieder, and Daniel Rigling. "Differential Transfer and Dissemination of Hypovirus and Nuclear and Mitochondrial Genomes of a Hypovirus-Infected Cryphonectria parasitica Strain after Introduction into a Natural Population." Appl Environ Microbiol. 2003 July; 69(7): 3767–3771. doi: 10.1128/AEM.69.7.3767-3771.2003.</ref>. |

Viral matter, contained within fungal vesicles, are poorly defined and consist of a nucleoprotein complex. The virus capsid is found in membranous vesicles. Virions measure 50-80 nm in diameter. Its envelope appears to have lipids; they are host-derived. |

Hypoviridae's genome is [[non-segmented]] and contains a single molecule of linear double-stranded [[RNA]]. The entire gene is 10000 to 13000 nucleotides in length. The 3' end has short a poly-A tail(of 20-30 nucleotides at the coding strand) <ref>Haiyan Lin, Xiuwan Lan, Hong Liao, Todd B. Parsley, Donald L. Nuss, and Baoshan Chen. "Genome Sequence, Full-Length Infectious cDNA Clone, and Mapping of Viral Double-Stranded RNA Accumulation Determinant of Hypovirus CHV1-EP721." J Virol. 2007 February; 81(4): 1813–1820.

Redirect to:
- From a monotypic taxon: This is a redirect from a monotypic virus taxon to its only lower-ranking member. In a biology-related article, when for example a family has only one genus, the family may be a redirect to the genus.
- Use {{R to monotypic taxon}} when making a redirect to a monotypic taxon from its only member, for example, from a species to the genus of which it is the only member.
- From a merge: This is a redirect from a page that was merged into another page. This redirect was kept in order to preserve the edit history of this page after its content was merged into the content of the target page. Please do not remove the tag that generates this text (unless the need to recreate content on this page has been demonstrated) or delete this page.
- For redirects with substantive page histories that did not result from page merges use {{R with history}} instead.
