To clarify the types of viruses present in various edible mushrooms during production， high-throughput sequencing technology was employed to detect fungal viruses in 53 strains of Pleurotus spp.， 10 strains of Ganoderma spp.， 17 strains of Flammulina filiformis， and 12 strains of Coprinus comatus.PCR amplification and sequence analysis were performed on newly identified potential viruses， and phylogenetic tree analyses were conducted based on sequence comparisons.BLASTx sequence alignment results indicated that a total of 51 contigs were annotated as 41 viruses detected from 92 strains of four types of edible mushrooms.Thirteen potential novel viruses were identified through RT-PCR amplification and sequence analysis， including seven species found in Pleurotus spp.， three species in Coprinus comatus， one species in Flammulina filiformis， and two species in Ganoderma spp..Phylogenetic analyses showed that these viruses belong to +ssRNA viruses， -ssRNA viruses， and dsRNA viruses， distributed across wight viral families： Barnaviridae， Botourmiaviridae， Deltaflexiviridae， Mymonaviridae， Partitiviridae， Phenuiviridae， Phlegiviridae， and an unclassified member of the order Bunyavirales.In conclusion， there is a relatively abundant presence of fungal viruses in the four types of edible mushrooms.
