Destroy a gameobject from a script on a different game object by tag?

I have an empty game object called GameController, with a script attached by the same name. Here is an exerpt from that script that applies to this question

void Update ()
    {
        if (restart)
        {
            if (Input.GetKeyDown (KeyCode.R))
            {
                Application.LoadLevel (Application.loadedLevel);
            }
        }
    }

I want this script to destroy a GUIText tagged “IText” when R is pressed. This would go under the input.getkeydown If statement, but when I add

Destroy(gameObject.tag  = "IText");

below the application.loadlevel, I get a bunch of errors. How should I be wording this

You need:
Destroy (GameObject.FindWithTag(“IText”));
