Item #6, clutch boot, about $42.
Like was mentioned, if it is not torn, you should be able to re-seat it. If not then a new one is in order.
There is supposed to be some gear box lube within the boot to lubricate the push-rod "piston" aka throw-out bearing....
Would it hurt to ride? Not really but that's your call. It's only going to drip oil into the path of your rear tire.......
