lunger

A wad of mucus that has been brought up from the lungs.

The act of a deep, productive cough followed by spitting out the wad of mucus is called "hocking a lunger", where "to hock" is a modern wearing-down of the original "to hawk".

Those suffering or recovering from pneumonia can hock frequent, prodigious, and frightening lungers.

I hocked a lunger up to the ceiling in the gym shower last week and it's still hanging there.
