The pilot reported that, during the takeoff roll from a wet turf runway, the airplane encountered mud, and veered left. He applied aft pressure to the stick and the airplane climbed into ground-effect. The pilot "pulled up" and attempted to climb out of ground effect, but the airplane descended and collided with trees.

The airplane sustained substantial damage to both wings and the fuselage.

The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
