A brilliant and almost fluorescent yellow-green extra-terrestrial growth caught my eye. It is a moss-like lichen that clings to the bark and wood of living and dead trees throughout the world, from sea level to the woodland edge. Historically wolf lichen was incorrectly known as wolf moss and it was dried and ground into powder, before being sprinkled on meat to poison wolves and foxes. Lichens grow extremely slowly, increasing imperceptible amounts in a year—only about four millimetres.
