This is the 15th year of continuous daily publication for 365Caws. All things considered, it's likely it will be the last year as it is becoming increasingly difficult for me to find interesting material. However, I hope that I may have inspired someone to a greater curiosity about the natural world with my natural history posts, or encouraged a novice weaver or needleworker. If so, I've done what I set out to do.

Evernia Prunastri And Usnea Scabrata
Day 365: I often refer to lichens as the "wildflowers of winter," in part because that's when many of them form their fruiting bodies, but largely because that's when they're at their best. Even after a hot, dry summer, a little rain and a few humid days is all it takes to restore them to their former vigour. Some, like Evernia prunastri (foreground) and Usnea scabrata (behind it and in the background) will be so stiff and crisp at the end of the summer season that they crackle underfoot, but soon return to a pliable, sometimes even limp state once they have absorbed sufficient moisture. As with these three here (a Parmelia is just barely visible left of the yellow leaf), mixed species often share the same substrate, everyone getting along famously, no one competing for dominance. I'll leave you with that thought as Year 9 of this blog closes. Don't worry. I'll be back.
