Wrong citation? What should I do? PLEASE SEE CLARIFICATION BELOW

I noticed that one of my citations is "problematic". It is from a book, but I found a Scopus reference that show it as a conference paper, with no authors. So I thought it was simply a mistake (because the paper is very old) and added the authors of the book normally, as the book or paper were published on the same year and the chapters are in fact other revision papers, but they are all the same. 

Now it came to my attention that the "authors" are in fact the editors of the book/paper, and I don't know whether I have done something wrong or not by citing them. If someone looks the reference using the "authors", volume and year they will find normally the book, but not the journal I referenced in the paper, which is from the same publisher as the book. 

Would it look like plagiarism or another ethical problem just because I mixed the two references, which are identical, but are written differently?

EDIT To be more clear, my citation is similar as if I cited a whole issue of Science (Science, 4, 2010) with the author name appearing as the editors of that particular issue.
You honestly attempted to make a citation, but made some mistakes in providing the correct information. This happens sometimes and absolutely is not plagiarism because you were clearly not trying to pass off others’ work as yours.

What you are responsible for is making sure the error is fixed. If the manuscript has not been published then all you need to do is correct the reference in a revision or at the proof stage. If the article has been published you should contact the editors for guidance about the best way to proceed.
