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.

Penny Perspectives - Baeomyces Rufus
Day 101: Although not as small as some lichens, the fruiting bodies of Baeomyces rufus (Brown Beret) are still tiny things, as this Penny Perspective demonstrates. The white stalks (podetia) and their tan caps (spore-producing apothecia) are only part of the lichen. The thallus (main body) is the pale green crust from which they arise. This species can be found growing on rock in shady locations. A similar species (Dibaes baeomyces) has a white thallus, and grows on soil.
When I set off on the Bud Blancher Trail a few days ago, my goal was a particular tree by the river which I knew to hold Graphis scripta, but as Crow plans are wont to do, this one began developing new legs almost as soon as my foot struck the ground. "Baeomyces!" I said to myself, thinking of potential material for a natural-history post, but I didn't think the "sucker hole" overhead was wide enough to allow me to reach the far end of the trail where I knew the species occurred. Then I remembered the second location, somewhat closer. When I got there, I was dismayed to find that the Baeomyces rock had been entirely overgrown with English Ivy in the space of a year. It took a bit of searching, but I finally found this last outpost of Brown Berets under a tangle of blackberry vines.

Baeomyces Rufus, Brown Berets
Day 98: It's always a thrill for me to find and identify a new lichen for my Life List ("and identify" is the qualifier), but I am a little ashamed to admit that this this dense colony of Baeomyces rufus (Brown Beret Lichen) was growing on a group of Cladonia-bearing rocks which I have studied minutely on several occasions. How did I overlook it? It may have been that the apothecia were just developing and I may have dismissed it for Icmadophila ericetorum, guilty of the sin of not looking closely enough to see the white podetia beneath the pinkish-tan berets. Icmadophila ericetorum is stalkless, but also grows from a pale green thallus (one of the most peculiar colours I've witnessed in nature). Baeomyces' thallus is slightly more yellowish, and at least with these specimens, less uniform. Under a magnifier, the thallus is revealed to be finely squamulose (scaly) or warty, but it's those little white stalks which set this species apart from Icmadophila and give away its true identity. Suffice to say that finding it in profusion at this location was quite a surprise! That'll teach me to pay attention to the whole picture, and not just the first thing which catches my eye.
