I think the OP is talking about the file type that Nautilus reports when
you right-click on a file and bring up the 'Properties' dialog.

In my case (also CentOS 6) Naulitus reports 'Genesis ROM' for files with
the .md extension. The file command, on the other hand, reports 'ASCII
English text'.

The file responsible for the behaviour of Nautilus is
/usr/share/mime/application/x-genesis-rom.xml, which appears to have
been generated by update-mime-database.
