Help Identify Disease of Mints Please

Can anyone identify and recommend a control for a condition affecting my mint plants
(oregano, monarda (2 species), and mentha piperites?)  All have brown leaf spots about
1/16" wide.  On plants severely infected, the spots merge so that the leaf is completely
brown, papery, dry-looking and sometimes shriveled.  The agent shows a marked preference
for mints, but I have also seen it or something quite like it on verbenas and borages.

Thanks for any suggestions.
