From the manpage:

``The mtree utility compares the file hierarchy rooted in the
current directory against a specification read from the standard
input.  Messages are written to the standard output for any files
whose characteristics do not match the specifications, or which
are missing from either the file hierarchy or the specification.''

So you run mtree twice, once against dir1 with the -c option to output the 
specification for the directory tree to stdout (which you can capture to a 
file, or pipe straight into the second invocation) and once against dir2 with 
the output of the first one as input (either in a pipeline, or by using -f 
with the filename of the captured output).
