1300 hours. The Evergreen State College Beach trail. Starting at parking lot F. It has been cold and raining. The morning was beautiful and sunny at 9 degrees Celsius but when we started the walk it began to rain on us and the clouds rolled in. John Villella was our guest today and he took us for a nice Bryophyte walk. When we first began to walk along the trail the habitat was mostly deciduous trees, Salal, and Ivy. We stopped at a Big Leaf Maple tree and John mentioned there were probably 30 species of Bryophytes on that tree. I admired the amount of diversity on just that one tree. We looked at Porella and Orthotrichum. I collected an Orthotrichem off of a fallen Maple twig. I also collected a liverwort that look like it had tiny hands when examined under the hand lens. We passed by an over turned stump and I collected what I have been told was Atrichum selwynii. I will take it back to the lab to determine if that was the correct species. It was a small acrocarp growing amongst many more individuals. We examined the stump and John found many small and somewhat rare mosses. Along the stream bank we examined liverworts and discussed the differences of morphologies among the same family of liverworts and I found that to be very interesting. I collected a red-brown liverwort off of a Maple tree. I also collected a large, green, wet liverwort off of the same Maple tree.
