Perhaps some Lutherans have simply thrown up their hands in resignation and let the term be used to describe their actually rather more mystical and less philosophical doctrine, at least as a way to distinguish the Lutheran position from the Roman.  Nevertheless, consubstantiation is not the Lutheran doctrine. It may well be the case that some Lutherans believe in the idea, as do some Roman Catholics, some Anglicans, and some Orthodox.  Yet none of these Churches actually teaches the doctrine of consubstantiation officially.  The instrumental documents of full communion between Lutherans and Anglicans make no mention of the term, and affirm that Lutherans and Anglicans share a common faith about he Eucharist (again, see Real Presence and metousiosis). The Book of Concord makes no mention of the word "consubstantiation" and, in fact, repeatedly and explcitly states the objective Real Presence  that "the true Body and Blood of Christ is present in, with, and under the forms" of the bread and wine, after they are consecrated.
