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.

Multicolored Rim Lichen, Lecanora Pacifica
Day 117: If it hadn't been for that Pygmy Owl stealing the show, this would have been yesterday's post. It too is a "life list sighting," the first instance of Lecanora pacifica (Multicolored Rim Lichen) I have found. In fact, it is the first of any rim lichen I've seen, and I could find no other examples of it on any nearby tree. It is purported to be the most common Lecanora on the west coast, occurring on a variety of smooth-barked deciduous trees. Its host in this case was Alnus rubra (Red Alder) and the tree was a lichen-lover's paradise, six or eight species all occurring within the bounds of approximately six square inches of bark. The largest of these apothecial disks was no wider than 1.5 mm.
