Either I have not seen lichens growing on glass before or just not noticed them, but today an old bottle caught my eye. It not only is nicely decorated with lichen, but there are two different kinds of them on it. I wonder if perhaps there may be a little greenhouse heating effect inside the bottle, making the glass a little warmer than the surrounding air because the lichens seem to be extraordinarily robust. (The decorated bottle was so pretty that I wanted to take it home, but I certainly couldn’t destroy their little world.)
Nearby there frost crystals on some barberry leaves, but I saw no frost on the bottle.
