Not too often someone shows up around here with something new, but I've never seen that one before. It looks exactly like roots on a fresh cutting, crazy man.

Can you give us any other specs? How old is the plant? From seed I'm assuming? Have you tried to clone it, (i would have to imagine it would root easily)? Was the bottom of the plant so thick that the stem was left in near darkness? Anything to deduce the reason it happened would be cool.

Very interesting specimen you have there either way:thumbsup:

Just saw your post, I would have to imagine if it were some kind of parasite you would most definitely see some kind of adverse reaction from the plant. I don't think you have anything to worry about.
