Near midair collision. Approach controller alerted reporter to traffic, but reporter idented a different aircraft as the traffic. When reporter was very close to traffic he had to take evasive action and contacted the controller who told him the aircraft in conflict had filed an IFR clearance. Shortly thereafter the other aircraft called for clearance. Reporter says controller should have been aware of the conflict and notified him.

Narrative:
I was on a descent to 2000 ft MSL as instructed by the controller on a 350 degree assigned heading. The controller informed me of traffic at my 12 to 1 O'clock at 1400 ft. He didn't say the direction or if the target was climbing or descending. He merely said it looked like it was in the pattern at X51. So I started looking and saw a kingair descending to land on runway 18 at X51. I said I had the traffic in sight. Approximately 30- 45 seconds later I looked out over the glareshield to see the vertical stabilizer of another aircraft extremely close to me. At the time I was descending and he was climbing so I quickly saw the whole airplane, immediately turned to the right, leveled off and told the controller of the situation. He said a C310 was on file for an IFR flight plan 30 mins earlier out of X51. Right after that the C310 called my controller for his IFR clearance. I think this could have been prevented if the controller had told me more information about the traffic (ie, climb, descent, heading, etc). Also if the other aircraft had gotten his clearance on the ground or over the phone.
Original NASA ASRS Text
Title: NMAC. APCH CTLR ALERTED RPTR TO TFC, BUT RPTR IDENTED A DIFFERENT ACFT AS THE TFC. WHEN RPTR WAS VERY CLOSE TO TFC HE HAD TO TAKE EVASIVE ACTION AND CONTACTED THE CTLR WHO TOLD HIM THE ACFT IN CONFLICT HAD FILED AN IFR CLRNC. SHORTLY THEREAFTER THE OTHER ACFT CALLED FOR CLRNC. RPTR SAYS CTLR SHOULD HAVE BEEN AWARE OF THE CONFLICT AND NOTIFIED HIM.
Narrative: I WAS ON A DSCNT TO 2000 FT MSL AS INSTRUCTED BY THE CTLR ON A 350 DEG ASSIGNED HDG. THE CTLR INFORMED ME OF TFC AT MY 12 TO 1 O'CLOCK AT 1400 FT. HE DIDN'T SAY THE DIRECTION OR IF THE TARGET WAS CLBING OR DSNDING. HE MERELY SAID IT LOOKED LIKE IT WAS IN THE PATTERN AT X51. SO I STARTED LOOKING AND SAW A KINGAIR DSNDING TO LAND ON RWY 18 AT X51. I SAID I HAD THE TFC IN SIGHT. APPROX 30- 45 SECONDS LATER I LOOKED OUT OVER THE GLARESHIELD TO SEE THE VERT STABILIZER OF ANOTHER ACFT EXTREMELY CLOSE TO ME. AT THE TIME I WAS DSNDING AND HE WAS CLBING SO I QUICKLY SAW THE WHOLE AIRPLANE, IMMEDIATELY TURNED TO THE R, LEVELED OFF AND TOLD THE CTLR OF THE SIT. HE SAID A C310 WAS ON FILE FOR AN IFR FLT PLAN 30 MINS EARLIER OUT OF X51. RIGHT AFTER THAT THE C310 CALLED MY CTLR FOR HIS IFR CLRNC. I THINK THIS COULD HAVE BEEN PREVENTED IF THE CTLR HAD TOLD ME MORE INFO ABOUT THE TFC (IE, CLB, DSCNT, HDG, ETC). ALSO IF THE OTHER ACFT HAD GOTTEN HIS CLRNC ON THE GND OR OVER THE PHONE.
