What do you mean by the Lamentations of the Mother of God?
The Lamentations of Jerusalem Matins, generally sung on Holy Friday evening, are not particularly Marian in tone.
There is a Canon of the Lamentations of the Theotokos on Compline on Great Friday in the Lenten Triodion by Met. Kallistos Ware and the late Mother Mary of Bussy. (I think this has been reprinted by St. Tikhon's Press.)
By Office of Consolation, do you mean the Paraclisis Canon to the Theotokos, frequently chanted during the first two weeks of August? There are several editions of that, but it's not generally called anything but Paraclisis.
