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!

Natural Art
Day 65: As a scientist, I am always picking things up to get a closer look, maybe using a magnifier, sometimes even nicking a small sample for examination under the microscope. However, that doesn't mean that I can't appreciate natural art when I find it. While most of Mother Nature's handiwork seems rather random to the human aesthetic sense, occasionally she elects to bridge the gap with something more to our tastes: balanced arrangements, colours which compliment one another, mixtures of visually appealing textures, etc. Admittedly, sometimes the line between science and art is blurry, and in those cases, I nearly always allow the right brain its moment of appreciation before permitting my analytical tendencies to dominate. In this particular instance, I'd been looking closely at a specimen of fungus, but when I raised my head and noticed this fragment of lichen (Evernia prunastri) perfectly laid out on a bed of decaying cottonwood leaves, science took a back seat. Its dichotomously branched lobes were artfully displayed, as if to illustrate the definition of the term on its page in the living encyclopedia of the forest.

Separating The Sheep From The Goats
Day 105: While it's actually quite easy to distinguish Evernia prunastri (top) from Hypogymnia inactiva (bottom) using only field characteristics, many lichens require reagent testing to achieve an accurate identification. Since some of the reagents commonly used have a shelf life of mere minutes, the amateur lichenologist is at something of a disadvantage. We often resort to placing "sp." ("species") at the end of the scientific name (as in "Hypogymnia sp.") when we are unable to test our specimens or narrow an identification down by location or substrate. That's "close enough for government work" when you don't have laboratory faciilities available.
