I also found this?
What is it? The petioles appear swollen which is a characteristic of some mustards and this bit of the plant was more cold hardy surviving a frost that wilted the rest of the plant. Not only that but it looks to me like a gall?
I broke it open and it is made of spongy tissue with no buggy inside that I could find. What is it? From the information I have found, I think it might be a gall from a swede midge.
Any clues?

Have you tried to look for a source of pheromone traps?
It looks like a nasty problem, I hope you don't have them. Do you rotate your brassicas?
Yes, I rotate them and I haven't noted damage similar on anything else. I haven't looked into pheromone traps though I might just do that if I notice anything else similar that might suggest the pest. I'm hoping it's not the swede midge as I haven't seen any reports in Ottawa but they are in Ontario.
Apparently they are in Europe. Have you ever encountered them?
