Hi Lynn! Your Asiatic type lily probably did get too much water this spring. And it may have also picked up a fungal infection known as botrytis. When it is done blooming you can cut off the stem close to the ground since it essentially has no leaves left. Throw stem and leaves in garbage; don't compost. The lily should come back next year, perhaps a bit weaker.
Some lilies are simply more susceptible to botrytis than others. The one to the left is from a different lily group, an Oriental lily, probably Star Gazer or some other lily with L. speciosum in its genes.
