NMAC occurred in autopilot cruise at 9;000 ft. in VMC. I looked up to see traffic at approximately 11 o'clock approaching me head-on. I estimate the traffic was between 400 to 500 ft. below my altitude and 200 to 300 ft. to my left. In the time it took to recognize the situation; the traffic had already passed behind me; and I did not see it again. I immediately advised ZFW; including color and type of aircraft. At first; the Center controller did not see anyone else on radar; but after a moment said he could see a primary target with no transponder information right behind me. He did not inquire further; and my flight continued normally.
GA pilot flying reported an NMAC without a traffic alert from ATC.
