Narrative:
I was advised of VFR traffic (small aircraft Y) northeast bound 5500' at 2 mi. I was eastbound IMC and advised controller of same. I returned to VMC and saw small aircraft Y descending and converging. I climbed to clear him and requested a 180 degree heading for avoidance while turning to avoid small aircraft Y. I was advised by controller that my mode C indicated 5300'. The climb was needed to avoid midair. Small aircraft Y was not under the control of the controller. I had just advised him 'no contact, I am IMC.' small aircraft Y was trying to avoid clouds but was not in layer VFR conditions. The controller should not assume that a 500' sep will be adequate or that the VFR aircraft will hold its altitude. He should have vectored me for avoidance early.

Title: REPORTER HAS LESS SEVERE AIRBORNE CONFLICT WITH AN SMA THAT IS DODGING CLOUD ALONG AN AIRWAY.
Narrative: I WAS ADVISED OF VFR TFC (SMA Y) NE BOUND 5500' AT 2 MI. I WAS EBND IMC AND ADVISED CTLR OF SAME. I RETURNED TO VMC AND SAW SMA Y DSNDING AND CONVERGING. I CLBED TO CLR HIM AND REQUESTED A 180 DEG HDG FOR AVOIDANCE WHILE TURNING TO AVOID SMA Y. I WAS ADVISED BY CTLR THAT MY MODE C INDICATED 5300'. THE CLB WAS NEEDED TO AVOID MIDAIR. SMA Y WAS NOT UNDER THE CTL OF THE CTLR. I HAD JUST ADVISED HIM 'NO CONTACT, I AM IMC.' SMA Y WAS TRYING TO AVOID CLOUDS BUT WAS NOT IN LAYER VFR CONDITIONS. THE CTLR SHOULD NOT ASSUME THAT A 500' SEP WILL BE ADEQUATE OR THAT THE VFR ACFT WILL HOLD ITS ALT. HE SHOULD HAVE VECTORED ME FOR AVOIDANCE EARLY.
