It is probably still fermenting. Odds are it is NOT mold. Sometimes during a very active fermentation, a little juice comes out with the CO2 and can get caked up on the slit. You can very easily take the bottle over to the sink and rinse that off with hot water.
Was your bottle really, really full? That might've lent itself to some juice coming out. I usually only fill a 2 litter bottle up to where the straight part of the bottle starts to curve upwards.
