Adjusting Event Font Size

My site is http://www.chcsek.org. I recently added the Event List plugin and put it in my left sidebar. I have other text in the same sidebar and have the Event List shortcode running below it. I’m trying to find where I can change the size of the font of the event name. I can’t find out where to make the adjustment in the Atahualpa options. Can you point me in the right direction?
