What is a word for "known incorrectly"?

I'm trying to organise a series of items, depending on whether these are known, unknown or known incorrectly to the observer.

I don't like the "know incorrectly" formulation. Is there a single word describing this?

PS: it seems the question was unclear. I am referring here to "known" as in "recognised". So I am categorising the objects as "recognised", "unrecognised" or "incorrectly recognised". (eg. you see the Eiffel Tower and shout "Look! The Bamiyan Buddha is still standing!")
