Played from the wrong tee

11-4 says you replay the shot from the proper teeing ground, and with a 2 shot penalty, so that sounds right. Of course, if the whites were less than 2 club lengths from the yellows, you could have got away with it...

Rule 11 - Teeing Ground

11-4 Playing from Outside Teeing Ground

a. Match Play

If a player, when starting a hole, plays a ball from outside the teeing ground, there is no penalty, but the opponent may immediately require the player to cancel the stroke and play a ball from within the teeing ground.

b. Stroke Play

If a competitor, when starting a hole, plays a ball from outside the teeing ground, he incurs a penalty of two strokes and must then play a ball from within the teeing ground.

If the competitor makes a stroke from the next teeing ground without first correcting his mistake or, in the case of the last hole of the round, leaves the putting green without first declaring his intention to correct his mistake, he is disqualified.

The stroke from outside the teeing ground and any subsequent strokes by the competitor on the hole prior to his correction of the mistake do not count in his score.
