There is a difference between {*$Variable} and {$Variable} :

  {*$Variable} : the $Variable for the currently browsed page, even if 
                 this markup is in an included page, sidebar or pagelist.
  {$Variable}  : the $Variable for physical page where the markup is.

In your teaser you probably want to use {$Description} and {$FullName}.

You may need to add this to config.php (if the above does not seem to work):
  $EnableRelativePageVars = 1;


P.S. If may be simpler and easier for your writers to set in the wiki page 
only things that could not be extracted in the pagelist. You can use in the 
pagelist template {=$Title}, {=$Description}, {=$FullName}, add {=$:image} 
and {=$:Summary}.

In the page:

(:title This is my title, note there is no : after title:)
(:Summary: This is my hidden subtitle:) or even
Summary: This is my visible subtitle

And in the pagelist:
(:if equal {<$Group}:)
 >>lframe width=600px<<
[[http://site/pics/{=$:image}"{=$Description}" -> {=$FullName} ]]\\
(:if equal {>$Group}:)

(also, \\ at the end of line means <br>).
