Help Deleting Radio Stations

If I go to my Playlists tab I can right-click on a song and select "New Station From Song" or "New Station From Artist." A song will start playing and I can go to the Radio tab and the new station is shown under Recently Played. The problem I'm having is there doesn't seem to be a way to delete a station I've created. Is there a place in Itunes to do this? If not, is the information stored in a file somewhere that can be edited to remove unwanted stations? I'm using Itunes 12.3.1.23 on Windows 8.1.
