Narrative:

Upon departing the holding pattern at mugzy descending and in a left turn, I observed out the left windscreen a glider in a right climbing turn. We never got a TCASII alert or ATC advisory. I would estimate a separation of 50-75 ft. I could see the glider pilot and into the cockpit. He never saw us. I took evasive action and initiated a sharp right turn and steep climb. We advised ATC of the event. This was very close to a disaster. I believe the glider operator was not practicing see and avoid techniques.
