The space of all complex structures on a surface, and the Deligne-Mumford compactification of this space, play an important role in many areas of mathematics. We give a combinatorial description of a space that is homotopy equivalent to the Deligne-Mumford compactification, in the case of surfaces with at least one puncture.
