..i have been observing similar objects for the
last year..

here is a pic from last year..







..they look very much like plants..but...
in reality they start as an extremely thin
[30 micron or so thick] fiber..that "stuff" grows
on..plumping it up to the point where it
looks..plant like. Best guess is that bacteria
of some sort are using the micro thin fiber as a scaffold.

..of course, the micro thin fibers themselves are not
normal...but hey..I've had them growing out of
my skin for two years now..apparently they are cellulose
fibers..utterly unbreakable by any acid, base or enzyme
that I've thrown at them...

I have been posting a lot of pics on this phenomena over at
the morgellons forum.

Since I have become vigilant to keep my urine pH
UP..somewhere near neutral as opposed to the dangerously
low level that was "normal" for me..[in the 5.5 range]..
the "really big plants" such as the one in the photo
are not getting so big. The stool is still loaded with
them, but they are much smaller.

..still looking for the right monkey wrench to break
the machinery that churns these out in large numbers.
