365Caws is now in its 14th year of publication, and was originally intended to end after 365 days. It has sometimes been difficult for me to find new material, particularly during the winter months, but now as I enter my own twilight years, I cannot guarantee that I will be able to provide daily posts. It is my hope that along the way I may have inspired someone to a greater curiosity about the natural world. If so, I can rest, content in the knowledge that my work here has been done.

Penny Perspectives - Graphis Scripta
Day 99: Graphis scripta (Common Script Lichen) is as elegant as its scientific name sounds. The Latin words mean "inscribed" or "written," and it does indeed look like pencilled scribbles where it appears on bark. It is known to occur on a variety of trees (birch, beech and others), but here in the Pacific Northwest, it is most commonly found on Red Alder. As you can see, it is quite small, but when viewed under a hand lens, the unique elongated fruiting bodies reveal a longitudinal split. Where grain lines appear in the bark, these lirellae often follow the path of bark texture. What secret messages are hidden in Graphis scripta's code? Are they telling you to get outside and take a closer, much closer look at Nature?
