I don't think it's mucoid plaque, I have done two blessed herbs Colon Cleanses in the last year and none of mucoid plaque I passed looked like this.
Jessesmom! the pics of "spiders & cotton balls" in that link were all too familiar and then I spotted the "more cotton balls" pic underneath and realised that I had passed something that looked like that too.
So it looks like they are probably Ascaris........ Gross
