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.

A Melanelia Among Usneas
Day 77: I am not sufficiently well-versed in distinguishing one Melanelia from another in the field to say positively that this is Melanelia fuliginosa (Shiny Camouflage Lichen), but it is either that or Melanelia/Melanelixia subaurifera. I lean toward M. fuliginosa because it was decidedly "shiny" compared to other species I have observed. In any event, it is one of only a few lichens which exhibit this particular brown colouration, and in either case, it may be tinged with orange or be somewhat closer to "Army green." It will be closely attached to its substrate, generally deciduous or coniferous tree bark, but also occasionally on acidic rock. Microscopic examination would reveal branched cylindrical isidia, but then I didn't bring a sample home. 'Sokay, I know where it lives.
