I am familiar with the mucoid plaque you talk about and the book by Richard Anderson. I did the cleanse called Arise and Shine and experienced rather quickly what is described as mucoid plaque. I used Bentonite and psyllium as well as two different combinations of herbs and a probiotic. It worked great but was rather scheduled. Bernard Jenson also discusses this mucoid plaque, but I followed Richard Anderson's book. Both of their books have photos of mucoid plaque and describe it as something obviously different from your stool and is rather difficult to cut or pull apart. (compared to stool) I definitely am not suggestion you play with your stool but if you use a hanger you can get an idea. The plaque I released was caramel color and actually looked like streched caramel.
Hope this gives you some insight...
