I'm assuming that this is what rampant HVX looks like on S&S -- correct? The last pic is earlier infection, I assume. These were three plants among perhaps 20 very large S&S, all jammed up together in a triple row.
If it's HVX, I'll print off info from the forum and make an appointment to talk to the nursery owner. They have maybe 200 large hostas altogether -- and I want to be sure of myself before approaching him.
My apologies for the out-of-focus pics -- I was trying to take them without being seen, and it's a new camera, so I didn't do very well!
