Never really noticed it before this year, but a few times I have

Anything to worry about and why?

Blight.

Is that always the cause of black marks? I now feel quite ill at some
spuds I've eaten.

Talking of which, I got a bag of king edwards a while ago from Sainsburys
that had something very wrong with them; sort of raised roundels that
looked like craters on an asteroid. I tried cooking a couple (yes, I am
rather dim) and they tasted horrible. I don't know anything about potato
diseases, but there was definitely something weird there, like some kind
of scab or something.

I trust you took them back!
