Apologies for the image quality....
No interactions present.
You could not rule out N. obliqua from the picture, though that species is strongly associated with Butterbur.
My Flickr photos...
According to NBN Gateway, no obliqua, or Butterbur have been recorded in VC53. Possibly it is podagrica. From what I understand the former was considered a rarity until its association with Butterbur was discovered.

I'd be amazed if there is no Butterbur in the whole of that Vice County?
obliqua seems to be found on any reasonably-sized bed of Butterbur where I am, but I have never taken it away from the plant. If you did not take yours from Butterbur, then it will almost certainly be podagrica. podagrica is very abundant on sites near me this year, far more than other years I can remember.
I don't recollect ever coming across the plant myself in VC53, that is not to say it is not present. In fact I am hoping that a search of ispot might show that it is.
