Bill, I can't view the first of your photos, your server returns an error message. However, I can see algae on the second photo. May be a root problem. You could try a fungicide good for phytopthera or pythium.
That looks to me too like one of the new N. hamata. no way have we ever shipped any of those labeled as N. vogelii. Just no chance IMO.
The hairy N. hamata are proving so far to be very difficult in cultivation. I think everyone agrees on that.
Did you ever buy a hairy N. hamata off Simon or anyone else?
