The white stuff in the toilet bowl sounds like candida. I have seen it like that in the toilet, but mostly I see it as threads, clumps of threads is the form it takes in its adult state. I see them at around 2 or 3 inches long these days, but a few months ago they were 5 or 6 inches long in great clumps matted in blackish BMs (Lovely!).
It can also have a jelly like appearance I believe, but when I see that Im not sure if its candida or mucous lining thats come away.
