A novel dsRNA virus was identified in the mycorrhizal fungus Thelephora terrestris (Ehrh.) and sequenced. This virus, named Thelephora terrestris virus 1 (TtV1), contains two reading frames in different frames but with the possibility that ORF2 could be translated as a fusion polyprotein after ribosomal -1 frameshifting. Picornavirus 2A-like motif, nudix hydrolase, phytoreovirus S7, and RdRp domains were found in a unique arrangement on the polyprotein. A new genus named Phlegivirus and containing TtV1, PgLV1, RfV1 and LeV is therefore proposed. Twenty species of oribatid mites were identified in soil material in the vicinity of T. terrestris. TtV1 was detected in large amounts in Steganacarus (Tropacarus) carinatus (C.L. Koch, 1841) and in much smaller amounts in Nothrus silvestris (Nicolet). This is the first description of mycovirus presence in oribatid mites.
