365Caws is now in its 16th year of publication. If I am unable to post daily, I hope readers who love the natural world and fiberarts will seize those days to read the older material. Remember that this has been my journey as well, so you may find errors in my identifications of plants. I have tried to correct them as I discover them. Likewise, I have refined fiberarts techniques and have adjusted recipes, so search by tags to find the most current information. And thank you for following me!

Ramalina Thrausta
Day 80: What a great way to start the new year! I picked up a lichen specimen on my way back from Sulphur Creek Falls yesterday after deciding that it was a Ramalina of some sort, and therefore a new genus for my unofficial lichen life list (or rather, that I found on my own instead of having one handed to me by an expert). Ramalinas are characterized by small perforations in the thallus; some species are so perforated that they look like lace. Although I couldn't see the holes with my naked eye, other details clued me in: both upper and lower surfaces were uniform in colour and the branches were flattened. I thought I might have trouble keying it out, but its growth habit and size quickly narrowed the options. Under the microscope, the perforations were visible, as well as a few very small patches of soredia. Bingo! At least I'd thought to take a picture of the tuft in the field, because by the time I got done picking it apart, it qualified as "specimen destroyed during analysis." May the joy of discovery be part of your life in 2019!
