Yes, i can identify it. Since it happened to me as well and i have pinned down the cause of it. Here is what is happening in terms of green mass: The reason your excrement is "Alien Green" or "Violent Green" both terms i like very much, is due to the Bentonite
you are consuming. You see the Bentonite
clay you are using has a zeolite rock quality to it, which is what colors just about everything it touches - GREEN. Especially Oil or oily materials. The fact that you are taking pro-biotics helps intensify this color. What i did was similar. I bought the clay, but i got the pure zeolite powder, the mediteranian variety. What i did was, I mixed it with Milk Whey and drank a heaping teaspoon-full of it in the Whey first thing in the morning. Next thing i know, a few hours later my excrements are completely DARK GREEN. No matter what i eat or even if i don't eat anything, as long as I take the zeolite/clay powder, my excrement is green. So, i mixed some with oil in a glass with the zeolite, as an experiment and guess what i see, the same Green color, and I mean really interesting Green, not like the Gallstones
green, but like what you are describing. I don't know if that's what you expected to hear, but this is the actual cause and if you cut out the Bentonite
you will see that the green will cease. Also, i think the green poo is a good thing because along with it, many weird things come out ;) I am thinking of mixing my zeolite with psyllium next time, to intensify the reaction.
Lots of Blessings to you,
