A friend pointed me to descriptions of a daylily problem called Spring Sickness. And since the first symptoms I saw were a stunting or twisting of the fan, I think it fits.
The following web site offers the latest information from a group of AHS Member volunteers who are working on the problem.

I don’t see any advice to remove the plants and there is some hope that as the season progresses, they may improve. I’ll wait and see.

I thought daylilies were easy! What’s eating them?
It’s going after the new growth but the centers of the older leaves have damage, too.
