That is what is commonly referred to as a leak.  Specifically on the main seal of the plunger, the one that creates all that nice pressure to disengage the mighty clutch springs.

A more significant question is where all that fluif is going.  It usually slithers down the actuating arm under the rubber boot, down onto your shoes or dripping off the pedal onto and under the carpet.

The cause is a deteriorated or worn rubber seal, possibly with or caused by pitting in the bore of the master cylinder.  The fix is to rebuild the cylinder if the bore is okay, or a new MC.
