The 355th (354 - 1 Fw 190D near salzwedel, Al White; 357 - 1 Do 335 damaged, Cooper and 1 Ar234 Destroyed, Riffle near Magdeburg, plus 1 Fw 190D, Cullerton, 2 Fw 190D, Long near Halberstadt) ranged from west of Berlin down toward Leipzig but didn't get anything on the ground.
I would speculate II./JG301 109D's were the ones around Halberstadt area. The one at Salzwedel was JGr 10.
