Have a problem with my corn

[Classicvette63]

I went out today to check on the garden an noticed something strange. On one of the ears of corn something was growing on the top of it. Easiest way to describe what it looks like is kinda like a brain. Grayish color and squiggley. It's firm and not a bug. What the heck is it? Should I remove that ear or the whole plant? Thanks
