Physcia dubia

Powder-tipped rosette lichen

I was helping a student learn to ID a common species of Physcia today, and was explaining the characteristics he needs to look out for, and at the end he was like "OK, so with all those things, there isn't another common lichen I can mix it up with, right?" Oh kid, I don't know how to tell you this, but even weathered, old lichenologists find IDing this genus so tricky as to name a species P. dubia (doubtful) to cover their ass if it turns out to not actually be a new species. This particularly dubious little fellow has an irregular or orbicular, foliose thallus that grows in patches up to 3-5 cm across. It has narrow, semi-attached lobes with a gray upper surface, pale margins, and a whitish lower surface. It has labriform (lip-shaped) soralia at the palmate lobe tips. Apothecia are uncommon, and have a sorediate margin and dark brown disc. P. dubia has a broad range and is common throughout the northern hemisphere, and has even been found at the southern edge of South America. It colonizes acidic rock and nutrient-enriched bark in urban and natural locales. Probably. Who can be sure, really.

Placolecis opaca

This lichen as a crustose-placodioid thallus, meaning that it grows in rosettes with lobes on the margin and areoles (tile-like subsections) in the center. The marginal lobes are elongate, branching, and slightly convex. The upper surface is olive to brown to black in coloration, and dotted with convex, black pycnidia. P. opaca produces black, lecideine apothecia. It grows on calcicolous rock in Mediterranean and submediterranean regions of Europe and Asia.
