haha i just joined your boat.
i found random Utrics in my pot of Nidiformis from JB.
just kinda popped up
i noticed em before, just passed em off as a weed or something.
then i noticed that creepa was talking about the same thing i had seen in my pots.
turns out they are U. Sandersonii or U. Livida xD
not sure what that is in your pic though. looks utric-like. but idk
