Credit goes to @pcareless for finding these beauties! I was looking at some half frozen Crematogaster sp. under a rock when I looked over and noticed that Phil was eating some things off the ground. He turned to me and said "Try this tasty crunch moss!" I assumed he was suffering from March Madness but he was right! They had the sweet crunchy tang of Buxbaumia! It was then that we came up with the idea for our forthcoming field guide entitled "A guide to identifying mosses by shoving them in your mouth"
