How do I subscribe to individual subforums on my google reader?

I am trying to subscribe to individual sub-forums, for example,

Physics Forums > Science Education > Homework & Coursework Questions> Advanced Physics

But I am not able to do it. The reader just gives me the feeds of the entire website. Anyone has any clues what I could do, preferrably in Google reader as I don't want to relocate all my feeds and bookmarks to a different location?

At forum display level there is a little orange rss button on the right side of the top bar on the first post.
