Lily symptomless virus actually can cause distinctive symptoms, including curl-stripe, in which leaves are severely twisted with yellow or pale green striping. The virus is aphid-transmitted.
Necrotic fleck disease is caused by a combination of Lily symptomless virus and Cucumber mosaic virus. Necrotic flecks, small areas of dead tissue, first appear as light spots parallel to the leaf veins, then turn brown. Cucumber mosaic virus is also spread by aphids.
