I should have been clearer, I am the lawn mowing contractor for the village. The worker who mowed that lawn was quite distressed over it when I told him what had happened. He thought he had done something wrong, but I assured him it was just one of those things that happen from time to time. Anyway we mowed it today. Didn't take too much off it. But it does look like something was applied to it. It's a mystery and real downer to the householder because he has put a lot of effort into his lawns.
