In the US you can't open a mag without reading, "Once upon a time..."
Seriously, though, (well semi-seriously) Just about all lits contain short stories, so do many other mags. If you subscribe to Writer's Market you can search under "fiction" and see what kind their looking for, pay rates, rights, etc.
Looks like you paid a whole lot of attention to writing, and little on marketing. If you can give some synopses of your pieces we might be able to focus in on a few.
