Fungal viruses, or mycoviruses, are commonly associated with symptomless infections in fungi. Mycoviruses are intracellularly transmitted during cell division, sporogenesis and cell fusion and their life cycles lack an extracellular phase. Their natural host ranges are limited to individuals within the same vegetative compatibility groups or those closely related. However, recent technological advances have allowed a few mycoviruses to establish experimental host ranges. While most known fungal viruses have double-stranded. Genomes of RNA (dsRNA) packaged in isometric particles are increasingly identified as mycoviruses with single-stranded RNA genomes. The best dsRNA mycoviruses belong to the Totiviridae family whose members are known to have simple undivided dsRNA genomes coding for a protein coat and an RNA-dependent polymerase. Mycoviruses with uncapsidated RNA genomes like hypoviruses and those with bacilliform (+) -strand RNA genomes like barnaviruses have more complex genomes and appear to have shared ancestry with potyvirus and sobemovirus lineages of plant (+) strand RNA viruses, respectively.
