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.

Cladonia Gracilis, Smooth Cladonia
Day 49: Although at least two other Cladonia species are making cameo appearances in this image, the star of the show is Cladonia gracilis ssp., Smooth Cladonia. The unbroken cortex ("skin") of the podetia is particularly diagnostic when attempting to separate this lichen from similar species in the field. The branched habit and specimen location strongly suggest subspecies turbinata, but I am reluctant to commit to that because no tests for lichen substances were performed. Had I remembered before 24 hours had elapsed that I had dropped an unprotected specimen in the pocket of my field bag, I might have been able to be more specific.
All right, I heard that. Which one of you laughed at the absent-minded professor?
