I'm always astounded by the the endless variations in form within this one variety of lichen--the Antlered perfume lichen (Evernia prunastri), if I'm not mistaken. The basic structure is always the same, yet each lichen is entirely different from the next. I want to understand this better.

I've mentioned the lichens you often see on the paths and roads in the two parks below. There are several different species of lichen in the two-park area, and even within one species, no two lichens are alike. Each one has its own personality.

Lichens often appear, as if from nowhere, on the paths in the parks.
