I would say it is defintaly UC. I could be wrong but IBS generly does not get mucus. This is caused by inflamation in the colon.
Actually.....IBS can produce tons of mucus.....(before IBS was coined a clinical term, it used to be called mucus colitis). Since the colon produces mucus naturally, over activity will also increase its production. It's mechanical, not autoimmune.
