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.

Usnea Apothecium
Day 169: An unidentified Usnea provided my second big thrill during the lichenology field trip. I simply adore lichens with "eyelashes" on their apothecia, and this was only the second one I've ever found. My previous discovery belonged to a different genus in which the fringed apothecia are common. In Usneas, it's something which is not too often seen around here. The largest "eye" (shown here) was roughly 5 mm in diameter. Two smaller ones were on a lateral branch of the same specimen. Upon closer examination, I believe two species of Usnea were present on this twig, although Usneas can be highly variable within a single species.
