One of my favourite fungi

Taken on 24 June 2013, right on the edge of a city park. I just love the cracked patterns on these fungi caps, each one different from the next. Wish I knew what kind they were. Before they "grow up", they are simply rounded, beige caps, that you probably wouldn't even look at twice. I did post a photo of a rather similar one a while ago, but wanted to add this one to my Fungi of Alberta 3 Set (when I've got it transferred to ipernity).
